just heard a new jailbreak has popped out of the oven. I ve never owned or jailbreaked iphone before , so just got a iphone 5 which is locked to a carrier but the seller didnt tell me that. So im thinking if i jailbreak it will there be any software (sooner or later) which can change the imei or unlock the carrier? I have seen there was something called (an app) Ziphone which unlocked the carrier instantly and for free. And since i dont know anything about jailbreaks (for apple) ive jailbreaked non apple products several times. But please tell me what will i miss out on using? Like if you jailbreak the PS3 you cant go online or use PSN What cons like these come with the jailbreak? ---------- And what is cydia?
