I'm having the same kinda problem, I have 3g on and i'm in a 3g area but for what ever reason the phone switches from the 3g to the edge network. The only thing I've been able to do is restart the phone, or turn 3g off then back on and its seems to work on 3g for awhile. By the way, its still locked.

Some SIM cards are not 3G compatible, just in case it's that. For example Orange UK have 2G-only SIMS. That would give you this problem.

Then I would take it into the shop where you bought it and show them that it does not receive 3G, get them to exchange it. Maybe the antenna has failed.
