Hey guys, I'm new to the forum so hello and nice to meet you all Great resource but my questions prompted me to join instead of just reading...anyway on to my questions: I'm not new to hacks as I've hacked things in the past like my PSP / DS / Xbox 360 etc but when it comes to the iPhone I've got a few concerns. These will most likely be basic questions but I'd appreciate a nudge in the right direction anyway: Q1. If you jailbreak an iPhone 3gs do any of the services work incorrectly?... The reason I ask is I'm from the UK and I have a contract with 02. I've still got about a year left so I want to make sure that by jailbreaking my phone I'm not going to cut off any existing services... (I'm thinking things like visual voicemail, and any wi-fi / edge related services)? Q2. Would 02 be able to detect that my iPhone had been jailbreaked and would this result in any kind of trouble aside from the usual? Like might they terminate my contract or something? Q3. Finally, is it possible to completely factory restore your iPhone if the jailbreaking process goes wrong or you need to send it in for a replacement due to a hardware failure? Thanks guys and my apologies if this has already been posted, I used the search but found nothing regarding 02 users.
