[Q] Is there a way to REALLY enable UMTS/HSDPA in 1900 MHz on a T-Mobile USA HD2?

---

I've tried almost everythig to allow my T-Moblie HTC HD2 to connect to a UMTS/HSDPA in 1900 Mhz but it seems I can just connect to EDGE.

The HTC is an US T-Mobile, but I am living now in Colombia, I am using also a Nokia N95 and it connects perfectly to UMTS here.

Is there any way? Is there a radio that allows this?

BTW: I paid full price for the mobile, so it is not locked.

HELP!

no, there isn't.

the n95 supports 1900 umts, thats why it worked and the tmous doesn't.
