well i just ordered my 4s as i smashed my 3gs in a temper, after using symbian so loyaly for so long i decided to change to iOS for a while. Well got straight in and saved blobs and read up, love the command line so set up ssh and installed like crazy. Then the power button decided to stop functioning so i lost it.. Anyway now that the 4s has been out for a long time are there any hardware issues or versions to keep clear from.. Its coming from carphonewarehouse so should be unlocked
