Cydia and other things gone into hiding

[Vartra]

Because I thought I was about to do the trade-in deal Radio-Shack had offered this week I backed up my iPhone 3G and restored it as a new device to give them an essentially empty device. Needless to say I got in there and they were out of stock so I came home, restored from my back up and then went to jailbreakme.com. I had barely done more than started restoring my stuff from Cydia and added a new app for themes (Codethemed.com’s app for wirelessly transferring themes) (first one I had paid for through Cydia) when things went heywire. First apps wouldnt open, then they started disappearing. I hooked up and checked with iphonebrowser, it showed the app’s files still on my iphone. I figure they are hidden somehow, but darned if I can figure it out. I tried using the spotlight search to find them, but its not finding them. and now Cydia and the App Store have disappeared. If anyone can help, I’d greatly appreciate it.
