Just as the question say:
TMo SGS2 Qualcomm vs. SGS2 siblings (AT&T/Sprint) Exynos... Is it worth it?
Found this on the other forum that I found interesting, and could be a debatable topic:
The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere
AT&T SGSII

Any suggestions for sub $300 tablets with 3G/4G?
Maybe the Nexus 7 3G is the better option?
Suggest you be specific about what network you intend to use the device on.
I have the SCH-i905 and yes it works fine with CM10 but it is Verizon only and I have not seen any info on how to unlock it to use on other networks (have seen several posts asking, just never any definitive answers).

Thanks for the reply.
Either CDMA2000 or UMTS is ok for me.
So no unlock method for SCH-i905.
So I am keeping my Nexus 4, however I am in the market for a a phone for my wife. It has to work with T-Mobile and I would love to find her a HSPA+ compatible phone, however i am really confused on how to figure this out.
For example I am looking at this phone at GSMArena:
Sony Xperia T and they say these are the bandz:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
How do I know it will work with T-Mobile's HSPA+?
Any help will be appreciated.

Thanks bud, but that doesnt answer my question, I dont need to know what coverage is in my area, but more what phone is capable of using T-Mobile's HSPA+
Yes it will. T-Mobile used 1700 and 2100 for HSDPA.

Thanks EL Daddy! So if a phone lists those bands 1700/2100 that means it'll work with HSPA?
I ask because I am also looking at this phone the Xperia S and those bands are :
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100 - LT26i

That one will probably not work as I believe you need both the 1700 & 2100 to work ( up & downlink connection).

3G or UMTS is as follows;
2100 refers to Band I / IMT and is used in Europe and Asia
1900 refers to Band II / PCS and is used by AT&T in cities, and by T-Mobile (1900 migration).
1700 refers to Band IV / AWS and is used by T-Mobile (most HSPA service is still here).
850 refers to Band V / CLR and is used by AT&T in rural areas.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
T-Mobile is slowly moving HSPA from 1700 to 1900 to support unlocked iPhones and free up 1700 for LTE deployment.
I would look for a phone that supports both (1700 now, 1900 future) or it may have a short life span.

Awesome! I see now, so in order for the phone to work on HSPA it needs both 1700/2100 bandz. AAHHHHHH SWEET! Thanks guys I made sure to hit the thanks button on both of you!

Nexus 4 works great on T-mobiles HSPA+ . I regularly get 20.8 mbps down/2.5 mbps up.. and this is in a 1700/2100 mhz AWS area .. PDX area has not been refarmed to 1900mhz yet - and Nexus 4 supports both 1900 mhz HSPA+ and AWS HSPA+ - so no worries.

Just to clear up one thing. T-Mobile often refers to 2100 as the Download Frequency of AWS (Band IV), while most hardware manufactures reference 2100 as IMT (Band I). See column 2 in the wikipedia link I posted earlier.
I get both bands here in NYC (mostly AWS) and the speed is about the same on both (20 Mbps / 2.5 Mbps), but ping results are quite a bit lower on PCS.

I was thinking about buying me a open line LG Optimus G2 then bringing it to japan, and give it as a gift. Ive been doing some research on the net, and it says that Japan doesnt support of use GSM frequency band, because they are not using 2G or something? Can someone please enlight me or explain this to me. How this things work, because i had already tried, and called the site here in norway that who are selling it. They told that it supposed to work but, after i have done my search on my own, i really doubt that what he told me. lol
So can somebody please or tell or can confirm to me that working or not?
These are the frequency band of LG Optimus G2: 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 900 / 1800 / 2100 / 2600 / 850
Thank you for your answer
Just got my Z3 compact yesterday and realized that it was the D5833 version which doesn't support T-Mobile band's for LTE in my area (US). I am having to return my package along with waiting for a D5803 version and my refund. Just be careful because this D5833 variant can give you trouble. It supported up to HSPA+ no problem by the way. Might work in other countries but not in the US for me. GL!
You can check the bands for the two Z3 Compact variants here:
http://www.gsmarena.com/sony_xperia_z3_compact-6538.php
2G bands
GSM 850 / 900 / 1800 / 1900 (D5803 / D5833)
3G bands
HSDPA 850 / 900 / 1700 / 1900 / 2100 - D5803
HSDPA 850 / 900 / 1900 / 2100 - D5833
4G bands
LTE 700/800/850/900/1700/1800/1900/2100/2600 - D5803
LTE 700 / 850 / 900 / 1800 / 2100 / 2600 - D5833
LTE 2300 TD-LTE - D5833
As a side note... the D5803 carries the bands for Verizon, but there is confirmed issues with using it on their system. The thread is in the Q&A section.
