Hey everyone! I have a jailbroken my iPhone 4.0.1 using Jailbreakme.com and unlocked my baseband (01.59.00) using ultrasn0w. NOW IF I update to 4.1 I will lose my jailbreak. BUT what about my unlock? Is that gone? forever? Since limera1n came out recently, I can jailbreak it on 4.1 but CAN I unlock it with the updated baseband? "DO NOT USE LIMERA1N IF YOU USE THE ULTRASN0W CARRIER UNLOCK wait for PwnageTool to incorporate the limera1n exploit. This is so that you can avoid updating your baseband and losing the unlock (possibly forever)." - Dev Blog If you want to preserve your unlock - do you jailbreak ONLY with PwnageTools? To create a custom .ipsw? What does that quote exactly mean? Sorry I am just a little bit confused. THANK YOU SO MUCH!!!
