Edit Reason: Clarify battery removal issue

It's a problem with memory corruption, hopefully a temporary/transient issue (like a passing cosmic ray) but it could be bad hardware:

There's a recessed hardware reset button in the back of the phone that you can push in with a paperclip, so you might try that. Removing the battery while the phone is powered on can corrupt the modem firmware though early on I did it a couple of times with no ill effects. (Also it's possible to reinstall/update the modem firmware if needed.)
