[Q] Can't get 3G working Help please!

---

So I just got this brand new beauty and I can't get 3G working for T-Mobile US. T-Mobile US works on the 1700/2100 band. The ebay listing and the LG website also confirm it but the box only mentions (GSM 850/900/1800/1900 WCDMA 900/1900/2100). Any ideas? Below are my APN settings.

Name: T-Mobile US
APN: epc.tmobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MCC: 310
MNC: 260
APN Type: default,supl,mms

It's not gonna work, my OB only worked on EDGE in the US. It had 3G everywhere in Europe. Unfortunately I permanently bricked it, and sent it back to Europe for repair. I don't think I'll be going back to the OB until it gets support in the US.
