Not worth gettin it unlocked. half the features wont work.

If u want an Iphone just get it the normal way. At least you know everything will work (visual voicemail, youtube, email ect). It's down to £169 @ cpw now. and the tarrifs are much better. £35 for 60 mins and 500 texts and that includes unlimited data. (better then the standrad o2 tarrif)

Hi sorry Durster but this is not strictly true, I have first hand experience of an unlocked iPhone and you can use pretty much all the features you would have access to with O2 (the exception being Visual Voicemail as far as I'm aware).
