Any idea why the app is refusing to restart? This is what I get in
the Apple report:

iPhone Simulator 3.0 (138), iPhone OS 2.2.1 (5H11)
*** Terminating app due to uncaught exception
'NSInvalidArgumentException',
reason: '*** -[UITableViewCell initWithStyle:reuseIdentifier:]:
unrecognized selector sent to instance 0x530f10'
Does this mean that the message listed is being sent to something
that isn't a UITableViewCell? Is there away I can use that instance
number to track down that something?
Yes, that error means the object you're using at that moment is not
a UITableViewCell, since UITableViewCell obviously responds to to
initWithStyle:reuseIdentifier:.
Not exactly. The instance was a UITableViewCell at the time the
exception was created; the class name in the description comes from
the object itself. Possible errors include a memory smasher (that hit
the Objective-C runtime's data structures), or a race (the pointer was
not a UITableViewCell at the time the message was sent, but became one
before the exception was created).
The Object Allocation instrument can be configured to record the
history of the bad address. NSZombie may find memory management errors.
