Anyone seeing this? I have a never-been-hacked gen 1 iPhone running the 2.0 FW. I've had to do a complete restore of my iPhone 4 times (via the forced restore method). I regularly get "Application ... not installed because an unknown error occurred (0xE8000013)." message. The application identified is not consistent so I don't think its a specific app. If I restart the sync, the identified application installs ok. From searching the web, this alarm appears to have been common for people with hacked iPhones installing the firmware...but I haven't found any references regarding the 2.0 firmware.
