Hey NgU, I just received an iPhone 4 for Christmas and I had a question. I am currently on 6.0.1 and I was wondering if jail breaking will remove the unlock. The unlock isn't factory, it was previously locked to AT&T, I then took it to A Simple Mobile tech and he unlocked it (not GEVEY sim). Thank you and hope for a reply!
what exactly did he unlock it with?
If its a IMEI unlock (Factory Unlock) then go ahead and update.
If its any hardware unlock such as Gevey, R-Sim, GPP then just incase make sure you preserve your Baseband and update your iPhone. This can be done using Redsn0w, but you need to have your SHSH blobs saved
