Looking for suggestions. So I have a jailbreaked 2.2 3G iPhone. I'm getting ready to update to 2.21, so I'm trying to backup my phone first. Plugged it into my PC, which is my main iphone computer, and it would fail the backups, I'd get told the phone disconnected after sitting there for a few hours. I thought it was crappy PC/windows stuff, so tried it on my macbook, same thing, it'd sit there for hours saying it was syncing, then fail. Tried it on my work iMac today, after 3 hours the progress bar was moving once in a while, obviously very slowly, until I finally got the "phone disconnected" message. Looks like my last successful backup was early Feb. on the PC using the same cable, though I'd had some similar backup issues in the past. So not a computer specific issue, I restarted the phone before the iMac sync, tried with different version of itunes depending on which computer we're talking about, anything I should look at? If it's SW, if I tell it to upgrade to the official 2.2.1, will that leave my data intact and then try backing up then? I may have to try that.
