Hello all! I know this is a long post but it seems that it's usually important to be as detailed as possible in describing a situation like this. I updated my jailbroken iTouch from 3.0 to 3.1.3 today. I only had a couple of jailbroken apps - Categories and the GBA and NES emulators - so I didn't mind having them lost and having to redownload them. I therefore did an update to 3.1.3 through iTunes (NOT a restore) without deleting Cydia apps first, thus keeping all my data for my App Store Apps and losing only my Cydia apps. All as expected so far. I then re-jailbroke by using the methodology outlined at this link. I was able to reinstall Cydia, Categories, and the emulators without trouble. Now here's where the problems come in. First, the NES app starts for just a second then crashes back to the homescreen. Secondly, there's space missing on my device I can't account for. I have 10.5 BG free of 14.5 GB. Of that: 1.5 GB are apps (as determined by checking the size of my Mobile Applications folder on my C: drive) .8 GB are made up of e-books .2 GB are made up of videos iTunes doesn't report any "Other" things on the device - it lists all my used space as apps (about 3 GB). But the numbers from Windows Explorer just don't add up. I think I read something about a firmware update writing over the baseband (whatever that is) and that this could cause files to be invisible but still take up space. I used WinSCP to SSH into the device but there isn't a ROMs folder in the Media directory, so I wasn't sure. To recap for those skipping to the bottom: 1. NES app crashes after a few seconds 2. There is space I can't account for that is missing on the device. Thanks for any help anyone can provide. EDIT: Forgot to mention... the .8 GB of E-books are in the form of .doc and .pdf synced through Documents to Go. I DO have some other e-books through Stanza, WattPad, Kindle, and Barnes and Noble E-reader's apps, but I wouldn't think a handful of titles (only about 45) would amount to 1.5 gigs when I have about 1000 e-books through Docs to Go breaking less than a gig.
