Hello
The other day i surfed to google from my XDA exec.
mobile internet rocks!!
i was wondering how does google know that i surfed in from a pda, cause i think it sent me to
www.google.co.uk/pda
the web page probably detected your screen size and redirected you to a page that was more friendly to you PDA browser. i wish more sites would do this.
www.google.com/pda for us US residents.
LOL
Not the screen size but the type of your internet browser, in this case Pocket IE.
Correct--it's not the screen size.
Although a LOT of your information is sent over the wire, much more than most of us realize, your resolution information is unknown to most websites, unless you explicitly allow it to be given via some kind of an executable that transmits such information. An example would be an embedded ActiveX object in IE for Windows.
Back on topic, yes, your browser information is known, not only to Google, but to every other website you visit. Not only that, the website also knows where you came from (i.e. the http addy) and where you went when you left it. There's a whole bunch of information deemed to be private that we would rather keep to ourselves (such as our surfing habits) that's known to any website that installs a cookie (a common thing nowadays) on your computer.
This is also how Google knows where you are. For example, when I log on, Google send me to the local Saudi page at http://www.google.com.sa/ It knows this information by doing a reverse lookup on your IP address, and comparing it against known databases of geographically assigned IPs. Since IP addresses are assigned and tied to geographical locations, it's easy enough to do, although it's still very disconcerting to see.
Be careful folks, even your searching habits are being tracked by Google. I have nothing to hide, so I don't care, but many folks do. Witness the recent Federal inquiry into the searching habits of the users of major search engines. Yahoo and MSN gave up that information quickly enough but Google is resisting. I don't think it will be able to hold out for very long though.
Imagine...now the fact that you searched for p0rn on the 'net is well known to anyone in the know. Scary, isn't it?

thanks monakh
so google can detect both my mobile ip address (is there such a thing?) and my browser, correct?

Correct, through the referrer...

Only if you click a link on the site itself, -and- it is handled via a special handler.
No information is sent to a website when you leave it through e.g. a bookmark in your browser, or by typing in a new URL.
Please correct me if I'm wrong
You are correct.
hey i mailed myself (google account) using my adsl modem and using the gprs/3g connection to check the header to see if i could spot an originating ip address
i found one common ip address
Received: by 10.xy.za.b with HTTP; Sat, 18 Feb 2006 05:34:45 -0800 (PST)
i guess this is the google server, correct?
is there any way to prise the originating ip address from an email
That's why there is a registry hack to set Pocket Internet Explorer works like Internet Explorer 6.0.

Not entirely... I mean, you could - of course. But it also means that many sites will fail to send you PDA-specific content - which, with most plans/top-ups, means heavy costs.
Identifying PIE as IE6 is more used for stupid websites who check whether the browser is IE6 or above, regardless of whether that is actually required by the site.
There's three parts, the compatibility bit ('(Default) = Mozilla/4.0'), the browser string ('Version = MSIE 6.0') and the platform ('Platform = Windows NT 5.0'). If you leave the last bit intact ('Platform = Windows CE'), then you should still be able to get into stupid sites, while having PDA-friendly sites send you the PDA content.
oh i had not thought about the popups
i guess we wont get(suffer) popups with mobile ie5?
i just posted to this bulletin board to check my ip address
from the pc it looks like this 82.1a.bcd.efg
and fro my cda it looks like 193.abc.def.ghi
That's fine because presumably your mobile device and your home PC are on different networks so they sport different IPs.
IPs are a dead giveaway. In many cases, your position can be 'somewhat' and primitively triangulated to within 5 square miles of where you are. This may not be necessarily true for mobile networks, but those networks know where you are at all times anyway. In fact, there is now regulation in the US that mandates all handset makers to manufacture hardware with GPS functionality built-in. Between the two and a half dozen GPS satellites and your cellular network, you can run but you can't hide
This is, of course, so emergency services can reach you in time of need (in case you are unable to make the call to 911/999).
Of course...

Technically it's so they can find you if you do call 911/999/112/whathaveyou but are unable (due to injuries, or duress, etc.) to state your location.
Being able to find you at any time is an added perk but it needs court orders even if you have been reported and officially designated a "missing person". Getting such a court order can take many hours, being declared a missing person can take 24 hours up to 48 hours (depends on the country and exactly what reasons you have to believe the person in question is truely missing).

Ahh yes, I stand corrected.
It's so we CAN make the call and are unable to state the location. That WOULD make sense. However, like you said, there are legal hurdles, although at least in the U.S., they are fewer and far between.
is there any ip address list out there which tells me which ip addresses are allocated to which country?
are ip addresses bunched like telephone numbers
e.g. +1 is north america
+3 and +4 is europe
+96 & +97 middle east
nope, that's not how they work
organisations can get an IP from their service provider, who get blocks from their service providers, who get bigger blocks from places like RIPE, who in turn get huge blocks from ARIN.
But if it's a specific IP you're interested in, try VisualRoute
Hi all,
I am considering buying the i-mate JasJam for business use by field workers, to use a web based application for maintenance. One of my biggest concerns is the requirement to lock down components of the unit to prevent unauthorised use - for example:
- restrict PocketIE to only the webapp site
- disable video calling
- remove unneeded apps
- disable email
etc.
No one from our "friendly" carrier (Telstra) can help me out - I need to use their service as the 850MHz band NextG network has the coverage and range that I require. I know that you can restrict IE5/6 to one or more websites using content advisor, but can't find out if PocketIE has the same registry keys.
Before I get flamed for not allowing my field workers free and full access to the web (and the capabilities of the phone), Telstra's data charges in Australia are ridiculously expensive - $30 per month for 70Mb + 25c/Mb after. Since I am covering the data charges, I think it is only fair to pay for what is used for my business.
Has anyone had any experience in handset modifications after delivery?
Thanks,
Mark.

T-Mobile is the only operator to give customers the Mobile Internet for a fixed-price. We never charge our customer's more than they expect for their Mobile Internet in the UK.
Therefore you'll never need to worry about how many emails you've sent, how long you've been on-line or the ‘data / GB’s’
Browsing means looking at websites and checking email, but not watching videos, downloading files or playing games. We’ve got a fair use policy but ours means that you'll always be able to browse the internet, it’s only when you go over the fair use amount that you won’t be able to download, stream and watch video clips.
So Whats Changing? - From 1st February 2011 we will be aligning our fair use policies so our mobile internet service will have fair use of 500MB.
What Does This Mean? - We’ll always let you email and browse the internet and you’ll never pay more than you agree to. We do have a fair use policy but ours is there to make sure we deliver the best service possible to all our customers. This means that you’ll always be able to browse the internet.
So remember our Mobile Broadband and internet on your phone service is best used for browsing which means looking at your favorite websites like Facebook, Twitter, Gmail, BBC News and more, checking your email and looking for information, but not watching videos or downloading files.
If you want to download, stream and watch video clips, save that stuff for your home broadband.

Hello,
in the past few days a have been trying to connect my samsung i5801 to the university network through VPN.
This forum has been a giant source of information and therefore I was able to create the VPN-connection I need (thank you XDA!!!).
I am now able to read my Gmail and visit the Android-market but that is about it. Apparently it is nog possible to download apps or to check my other email-accounts, not even facebook. It is pretty important for me to have the internet connectivity, since I have to use the Pubmed-application in search of articles for my thesis and other papers.
Is there any way to make the VPN connection allow me to use the internet? Or is it more likely the problem lies with the ICT-coordination from the university? I have looked at other threads, but so far I haven't found a solution to my problem.
Oh, I use the app VPN Connections (v0.99) because my university uses Cisco.
Greetings,
Hi!
Anyone else bothered by sharing their personal info on social network to the third party? I had thought about developing open source distributed social network app based on https server running on android phones. Each member should have android device as a server of his/her profile.
0) - https protocol could provide possibility to connect to your social network using web browser.
1) - One may be able to deal with extensive upload and download or lost connection issues by allowing distributed profile updates sharing:
I suggest following scenario:
D updates profile. B, C are acknowledged friends of D. B is on quality link - good connectivity to internet and sends broadcast I am sitting on good connection. B downloads update of D. D looses connection. C downloads and update of D from B.
2) - Re-acknowledging of friend ship should be day-wise of few hour-wise. So passwords should change during time using some hashing or whatever.
what do you think?
see ya

I implemented such a prototype some year ago, although not for mobile clients. You'll have a few issues you'll need to address. You have to use PKI to ensure the identity of the sender in the distributed environment, and you'll have to implement a message routing protocol distributing the messages among the peers. Have a look at my prototype and feel free to steal any ideas: http://whisper.ping.se
Thanks!
Maybe for simplicity one could just copy WIFI WPA2 protocols where router would be one member and internet connection would be connection to the members personal data.

Huh? I'm sorry, but I can't make any sense of this at all. To achieve what..? I'm missing something here, I guess.
Android is shipped with the BouncyCastle crypto libraries. This is what you'll use to sign the messages with each users private keys to ensure the identity of the author of each message. If you want to encrypt, you'll use this library as well. Since you are working in a distributed store and forward environment, you can not rely on link encryption (e.g. https, wpa2 etc) but have to use point-to-point encryption instead, protecting the message itself instead of the transport channel.
Radio broadcasting resembles similarities to the internet "broadcasting" or: social network resembles similarities to the "person-his friends" virtual private network.
Since it is said that it is hard not to make security flaws when constructing new protocols. i think that adopting whole existing expert made protocol is best solution.
Whole wifi wpa2 protocols could be packed inside ordinary encrypted channel. Where the personal info provider of specific person from which his friends would want to download info - would take place of a "wifi Access Point " in this.
