Is there a way to do this? iPhone 5, iOS 6.1 using the Evasi0n 6 jailbreak. I went to the Apple store yesterday to replace a broken Lightning cable and the genius noticed that my battery was swelling on my iPhone. It's a no charge under AC+ replacement and she did not seem to be bothered (much less interested) in my obvious jailbreak. But if I can, I'd rather restore the phone before taking it in today (I made another appointment). But here's my problem. All of the Macs I own are PowerPC (iPhone 5 won't sync with PowerPC Macs and iTunes 10.6.3 is the highest I can use) and the two PCs I do own are in pieces right now. The closest PC or Intel Mac I could use is at work, but I'm on vacation and I'd really rather not go in unless I need to. My understanding is that attempting to restore on my iPhone will simply force a reboot of the phone that does nothing (because of the jailbreak). Without access to iTunes is this not possible. If it's not, then fine, I'll just take my chances, but if there is a more or less easy way to do this without iTunes I thought I'd ask.
