If you want a personal opinion, I would not buy a used T-mobile device for use on any carrier but T-Mobile if you want 3G.
Yep, but apparently my telco uses 2100Mhz for both upstream and downstream, which T-Mobile's 9700 supports. I'm just wondering if there's anything besides the frequency bands that differs between the two versions.. The UMTS protocols are otherwise the same right?
