Flip (clam shell) phone

[sprayer]

I have (and I wish I didn't) a Nokia 6600 clam shell phone that is forever going wrong, it is on contract
with O2 and still has about a year to run, I have decided to buy an unlocked secondhand phone and
put my sim card in that.
Somebody has offered me a Motorola RAZR v3i in good condition with all the accessories for £20.
As I particularly wanted a clam shell type phone this seemed to be quite a good deal, can anybody
offer any advice on this phone before I commit to buy it ?
