To use T-Mobile's 4G network you need the aws 1700 and 2100 bands. T-Mobile is going to start rolling out high speed data in the 1900 band but it may take some time depending where you live before you get these speeds so you will be on edge until then.
You will also need to manually enter T-Mobile's apn/data settings o receive data and mms.
Forgive me if this is somewhat of a rudimentary question, but you mean that I must find a phone that supports both the 1700 and 2100 bands if I want to use it on T-mobile and get their 4G speeds? Does it have to support both? Those Sony phones I mentioned support the 2100 band, but not the 1700, which is why I'm asking.
Also, and forgive me again, but what do you mean by manually entering the apn/data settings to receive data and mms? Looking under my current phone's settings(T-mobile G2), would that be under the Settings/Wireless & Networks/Mobile Networks menu? Is there a guide somewhere or a website that would tell me what T-mobile's settings are?
I sincerely thank you though for your help. I've been reading up on all these new phones coming out with dual core processors and high resolution screens and whatnot. I've had my G2 for close to 2 years now and I want to try a touch screen only phone(even though I would probably sorely miss the physical keyboard). There just haven't been many phones recently with physical keyboards that are actually good... Anyway, thanks again!
Tmobile uses the 1700 and 2100 data bands for their 4G data.Usually the only
phones found with those bands are Tmobile branded phones but there are
some unlocked phones out there with those bands.

As for the apn/data settings if you buy a phone unlocked the settings for Tmobile will not be included in the phones settings. If it's an Android phone the settings can be found here.
Personally I would just stick with a Tmobile branded phone. I have an Amaze and a Sensation I love both.
So to confirm, I would need to find a phone that supports BOTH the 1700 AND 2100 bands to get 4g speeds? The two Sony Xperia phones(Ion and Sola) I mentioned would only get Edge speeds if I tried using them with T-mobile currently?
And while I have a G2 at the moment, and I know it was made by HTC, I don't like the other phones HTC recently released. I like the design stylings of the newer Sony phones, and their build quality as well as the features and UI. Plus I like having a phone that not many other people have.
Sorry, but one last question. Is there any way of finding out when/if T-mobile will begin switching over to 4g data on the 1900 band in my area?
I just wish T-mobile had more Sony phones in their lineup, such as the Sony Xperia Ion. Or why couldn't Sony just include the 1700 MHz band in their phones. That's the only thing I do not like about T-mobile, it seems it's too hard to find a phone that will work 100% with their services...
Anyway, I thank you again for the help. I appreciate it!
