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)
