Has anyone gotten the SK17a (American version) to work on T-Mobile's 3G network (not 2G)? I am getting on 2G with this phone, and was told by Sony Ericsson support that the only U.S 3G network the phone works with is AT&T.

Does anyone have the SK17a (or SK17i) working on 3G T-Mobile?

Thanks in advance

I have both SK17i and SK17a; none of them works with 3G T-Mobile. They only work with 2G (EDGE)

What T-mobile support told you is correct.

The technical answer is because T-Mobile USA works under 1700 MHz/2100 MHz for UMTS/HSDPA (3G).
You need BOTH bands to work on 3G.

Mini pro sk17a works under:
HSDPA 900 / 2100 Mhz

and sk17i:
HSDPA 850 / 1900 / 2100 Mhz

As you can see, both versions lack the 1700 Mhz frequency band.

I'm still with T-Mobile, although I'm planning to change to AT&T next month...
