Walmart has 2 versions of the 521. One is T-Mobile branded and as we know, locked to T-Mobile.
Then there's another one, specifically described as "unlocked". The picture on their web site suggests that this is the MetroPCS version. Is it really unlocked? Others also carry this model of 521, including Best Buy and Frys, Are they all unlocked?
Seems like it should be possible to flash a T-Mo firmware from NaviFirm and get WiFi calling on an unlocked 521.
The specs on this thing don't definitely show UMTS 2100MHz support. Anyone tried a 521 n Europe and gotten 3G?
