AT&T/Cingular are in the process of rolling out their HSDPA network and a handful of cities are using it; NOW is the Universal capable of this....I asked a similar question about the UMTS 1900 MHz being activated so it could be used in the states; Granted I was given some very good replies but I am still curious. Over the past week I have been talking to some other engineers in my field and have found that a great number of things are possible with the Universal, it has the architecture to support this, SUPPOSEDLY ! Now lets look at UMTS as a whole; then HSDPA ! HSDPA is a software upgrade to existing UMTS software, that's all ! SO is it possible that we can have HSDPA on the Universal with an upgrade to the radio stack, I think YES !...and the bands should also be able to be activate, current UMTS 2100 MHz to 1900 MHz so it becomes dual band...the other is the GSM 850 band ! That apparently can be activated !...HOW is the big questions....Most of the HTC is limited by software; not hardware...its existing hardware has been built with scalability in mind...I just hope that some one can figure out the radio stack updates to facilitate this functionality !
The current model does not support HSDPA. However, I heard that the HSDPA version is due before year-end.

I am wonder if the radio in the JasJar will be able to support the Cingular US version of UMTS of 1900. Currently the device only has a setting for 2100. Is this just an update for the radio or am i hosed for living in the US.
your hosed
umts 2100 the rest of the world.
perhaps future versions of the mobiles with support 1900/2100 umts
Hi All,
is there anyway to determine what GSM frequency band a WM5 phone is currently using?
I would like to know if my WM5 device is using a 900 or 1800 MHz GSM band. The device is quad-band capable and the network I am on is dual-band 900/1800. I can't find any GSM hash codes to report the information and I've had a quick look through extended TAPI but can't see anything.
Building on from that is there anyway to force a WM5 device to only use 900 or 1800? i.e. the mobile would only report itself to the network as being 900 or 1800 capable...but not both.
Thanks, rhd
Hello to all
i have been searching a few known phone's that i like but i can't seem to find a phone that has gsm 2100 mhz band is this a new band on the gsm network thier for i have to wait for them to make gsm 2100 mhz band phone
Reason being i with tmobile and the 3g i been told by tmobile rep only works for tmobile on 2100Mhz gsm band
if possible is thier away to change or reprogram your phone for the band or is this hardware in the phone
sorry i'm quite ignorant to this network tower thing but trying to learn
thanks for you help
you might as well be going from analog to digital. its normally not just a software update.! its a complete hardware change. If you look at the iphone for example it has 3 radio chips in it all for different bands!
The physical hardware between these three models of phones are the same, yet they have slightly different radio ROM configurations set through firmware. My issue is that the 910c I am using has UMTS 850/1900/2100 MHz capabilities and I would like to use it on T-Mobile's 3G network which uses the UMTS 2100/1700 MHz. Has anyone tried to modify the frequency multiplier to substitute either the 850 or 1900 MHz for the 1700 MHz for use with T-Mobile?
Any solution yet?
I would like to be able to use 3G also with T-Mobile and have been looking endlessly, have you found a solution yet?
Don't expect such a solution - I've never heard of a successful radio ROM mod; all radio ROMs are issued by the OEM / manufacturer.
Have a look at the Qualcomm MSM6280 chipset datasheet - it seems the frequencies are probably hardcoded.
but how's talking about some qualcomm? HP has intel inside
Back in december 2010, my i9000 worked just fine on froyo, with an provider that operates on 850 mhz for GSM and 2100 mhz for 3G. My work made me move to another provider which operates in 1800 mhz for GSM and 850 mhz for 3G. Also, my phone was great. Gingerbread came and, as everyone else, I made my update (and of course changed the bootloaders). The problem: I'm back to my old provider again (850/2100 mhz) and, as strange as it may seem, my phone can't connect to the gsm frequency (850) anymore! The 3G works with no problem. I've tested lots of modems, configurations, I have even returned to froyo, with no positive response. It seems like my phone has never had the gsm 850 mhz option. What has happened? Is it possible that my GSM frequencies have changed (by software?) Does the bootloader have anything to do with this? I'm just as confused as I can be! And I need my phone to work! Help me please!
Edit: DID IT!!!! I don´t know what was currupted, but I did a full format : SD,Sys,Data,Cache and after that I made a new ECLAIR (JM9) install and.... voillà....2G 850Mhz working again! Txs for the attention!
