Phone Unlocking Sony Ericsson T630

Was thinking about getting the Sony Ericsson T630 from work tomorrow as an upgrade to my Panasonic GD95 but there seems to be mixed reviews about it. It seems a really high spec phone to me even though it's a bit low on memory and hasn't got a fantastic camera but some people seem to have problems with a weak signal and the phone hanging. Anyone with one of these that have had these problems? I need a phone with a decent signal because I live in a low signal area so I struggle for a signal.

My Panasonic seems to have a problem with hanging when it's turned on and sometimes even crashes so I leave it on 24/7 to avoid this but apart from that I'm happy with it but the shop I work in had some T630s in the other day and I really liked the look and spec of it. Anyone want to vouch for this phone? I'm not extremely fussed on features, just the overall performance of the phone... BLOBBY

Cheers

Also, does anyone know if it's possible to use your PC to answer a call using the speakers and a microphone with a bluetooth dongle?
