Right folks, I bought a second hand Iphone 3g a while ago as a cheap way of getting into the smartphone market without getting a contract. It's ex-UK Vodafone contract, and I bought it for use with a German pay-as-you-go sim card. No dramas so far, and I used it happily for several months with no problems. However, I was having problems getting a lot of apps to work on my phone due to the version of Ios I was using (3.1.2) so I connected the phone to Itunes to upgrade it. Wrong move. It is now stuck on the emergency screen and requires a sim-unlock to continue. Having done a bit of Googling I have found a lot of self-help guides, but many have been found to be scams while others no longer work due to Apple finally cottoning on to them and changing the system gizzards. Apple can help from what I've heard, but they will charge for the privilege. I don't mind paying as a last resort, but would prefer to have a stab myself first. Has anyone encountered this problem recently, and if so, how did you fix it?
