My Phone Just Loves to Hate Me

Ever since I came back from San Francisco, my phone has not been able to hold a charge for very long, even in standby. I've tried restarting the phone, drain cycling the phone, popping out the phone battery, etc. Nothing seemed to work.

Yesterday, my phone crashed, and after I rebooted it, it is no longer mysteriously draining the battery.

At first I thought it was a bad battery, but now I'm more inclined to think that it's just another problem with the OS.

In any case, it's got to be a sign. Mr. Rogers, where's my iPhone?
