So i want a new phone. I'm on Cingular's network, and i want a Sony Ericsson T68i.

I DO NOT want to pay for the phone from Cingular and be locked into their stupid contracts. And i don't want to be locked into Cingulars web/mail settings on the phone.

SO... what do you folks know about these "unlocked" cell phones you can get on ebay and locally? I get the general premise... it's not locked to a network so any SIM card can be used in it. Anyone ever go that route?

My options are to buy a locked phone and figure out how to unlock it... (any of you know how to do this?)... or to risk buying an unlocked one on Ebay or locally and pop the SIM from my current phone in it.

Opinions? Answers?

I want to decide this weekend as i can no longer stand my current phone
