I'm looking to buy a new iphone 3gs payg from apple UK. Done a load of searches so I think I've got my head around this jailbreaking then unlocking business. So I'm just waiting and hoping they are able to break the 3.1 firmware now. In the mean time can someone just check that my logic is correct and this is all possible before I go and blow a large chunk of my hard earned... So the plan is... Buy iphone 3gs payg and activate with sim card supplied. Jailbreak then unlock. Use UK T-mobile sim on my current monthly contract. This is the part i'm not so sure about... As I understand it at the moment if you have any problems with the phone and need to return it you just have to do a factory restore and it wipes out/ reverses any jailbreaking and unlocking so Apple are none the wiser and the warranty is still in tact? If they return it with an updated firmware would I still be able to load my backup back on? I'm guessing I could as long as the new firmware could still be jailbroken. Also the jailbreaking / unlocking has no ill effect on the phone whatsoever you just lose the visual voicemail feature? So you can still connect to itunes as usual, synching still works the same, and the apple app store is still accessible? This all seems to easy?
