That doesn't sound good at all. If its stuck in that mode. You may try removing the battery out for 1min and then re-try, but if the problem continues after that you may have to try a hard reset. A Hard reset will erase everything from the phone. Here are the steps

This information maybe to late.
Hope this helps.
Pink Elmo, fortunately I did not see your response before I managed to get to a Sprint store and they fixed it. And again, fortunately, I had all my phone numbers backed up on my google account (which I didn't know--how very smart of me) so I didn't lose a thing. I will keep your directions, however, in case the unthinkable happens (again!)
Thank you, anyway, and maybe your information will help someone else. Just remember everyone, when you are saving a phone number, save it to your google account, not the phone.
That is correct talkingbird. Also, from your Contacts or People app (depending on your device), Menu - Import/Export - Export to SD - Phone Contacts ~ will actually copy those "phone" contacts to the SD. By reversing this process and selecting "Import" instead, not only can you restore the non-synced "phone" contacts, but you can easily import them to Google instead of the phone just by selecting the Google Account during import. If you are not seeing a Google option for import, it means that your Gmail is not loaded yet as in right after a reset.
