The OP already stated that the phone is unlocked youngb...but I don't think that matters any more since you're banned, lol.
OP, you might have a defective phone. I have heard a bunch of problems with this one. Another thing to consider is that 850Mhz might be the signal that is in use where you live. The CF62T runs on 900/1800/1900, which T-Mobile mainly used just the 1900. That could be the reason why there is the constant "searching" on your phone. If you really like the look of this phone, I suggest you buy the US version, the CF63. Other than that, I'd probably recommend buying another phone cause that one will break down sooner than you think.
