Right now I am in Maui Hawaii visiting some family and I forgot my USB cable to plug into my Mac. I am charging it with an incase dual wall/car charger so I didn't bring my USB cable. I didn't think I would need it. So here it goes, my iPhone is jailbroken on 3.1.2 and I just want to restore it because it keeps freezing it's irritating me and my battery is draining like crazy and I know it is because my phone is jailbroken and I use backgrounder and kirake mainly. I would like to restore it back to normal. Any way possible I can do this without plugging it in to my computer since I don't have a USB with me? Thanks in advance for any help.
