Mine did the same, and found this on another topic, it got mine to the connect to itunes screen! Still trying to restore it tho!
1. Do a hard reset on the phone, hold the sleep/wake button + the home button until it turns off then release before it turns back on.
2. Plug the dock into the compute and have iTunes running.
3. HOLD the home button on the iPhone, while holding it, connect the iPhone onto the dock and CONTINUE to hold the home button until the CONNECT TO ITUNES DISPLAY APPEARS.
4. iTunes will recognize this and ask if you would like to restore it. Click restore. Then choose to restore from BACKUP! This will take a few minutes. It will fix the problem. Your iPhone will be up and running as normal and all your contacts, sms, bookmarks, settings, etc. will be intact. The only thing that will be erased is the music. But you can easily add that all back right.
