Hey Everyone, I've done a bunch of searching but can't seem to come up with any definitive answers. Any help would be much appreciated. I've got a Telus iPhone 4, untethered jailbreak iOs 5.1, baseband 04.12.01. I'm traveling out of the country in a couple of days and want to unlock it. I've looked at the carrier option through Telus, but it's $35 and I'm nervous about how the factory unlock works with a Jailbroken phone. The steps online say it has to be plugged in to iTunes. Can I use this unlock method if it's jailbroken? And if I unlock it and want to upgrade to iOS 6 jailbreak, will I lose the factory unlock? I've also looked at the SAM procedures, and that seems like it would be easiest, but I won't have my computer with me to plug my phone into iTunes. I don't have the other SIM card (I'll purchase it on arrival), so I can't do it before I leave. Is there a foolproof way to do a SAM unlock without iTunes? Any help would be much obliged.
