I'm getting the "iTunes could not backup because an error occurred" with no error code. I've tried reading everything I could find for different fixes and nothing has worked. Tried: force backup by right click and select backup Hard iPhone reset kill iTunes and apple processes, restart iTunes computer reboot uninstall iTunes, re-install, reboot pc delete photo cache from pc delete all iPhone backups from pc killed windows firewall It's a Verizon iPhone 4 running ios 4.2.6. I almost never sync to the pc but wanted a backup before upgrading to the newest ios. I'm sure I could restore to the newest ios but I don't want to loose everything. Any ideas? I'm wondering if it's a cydia app causing issues or something? Just searched that while typing and saw some possibilities. I'll still post this and report back with updates. Thanks for any help.
