Help with jailbreaking and Cydia for iPhones, iPads, and iPod touches.

evasi0n7 can jailbreak iOS 7.0-7.0.6 untethered. p0sixspwn can jailbreak iOS 6.1.3-6.1.5 untethered (see here for 6.1.6).
How to jailbreak iOS 7.0-7.0.6 (and fix problems). iOS 7.1.x is not jailbreakable, except an unsupported tethered iPhone 4 jailbreak.
Restoring or updating will update your device to iOS 7.1.1 and remove your jailbreak. There is no way to downgrade from iOS 7.1.x to 7.0.x.

Hey all,

I recently moved from Canada to New Zealand. I was using Rogers as a carrier in Canada and have just bought a Telecom SIM card. I went through the redsn0w jailbreak and installed Cydia. I unlocked it with ultrasn0w. The problem is, when I insert my new NZ SIM card I get a notification saying "Invalid SIM", followed by a big ole NO SERVICE. Any help would be appreciated. Let me know if anyone has any answers.

Cheers.

Yeah, I heard something about that. Wasn't sure if it was a good idea. Does downgrading your baseband adversely affect anything on your phone? And how do I go about downgrading my baseband?

Thanks

Buy an official unlock is better. You can use any carrier forever even you upgrade or restore
