Does jailbreak void my iPhone warranty?
Yes definitely. Jailbreaking your iPhone would void your warranty. So better consider your option of jailbreaking again. Don’t jailbreak your iPhone for silly reasons. If you need it to be jailbroken for unlocking from network restriction, You can try any other safe unlocking method which doesn’t involve with jailbreaking. For example, Youcan get the remote unlocking service from www.TheUnlockArena.com This method of unlocking doesn’t require a jailbreak. It is also a very safe and simple method too. Good luck mate.
