Im thinking of buying out of my contract early, just looking some advice. It'd cost me around £289 to get the phone on o2 on a £30 a month 18 month contract. selling my old iphone 3g should get me around £170 + I hope so would be reasonable. just wondering what the general concencious about getting the phone now is with the signal and proximity sensor issues. since im upgrading early I couldnt return the phone if i encounter these problems as o2 apparenrlt dont let you since its a known fault. would it be better to buy now or wait until november when my contracts up.
