When Will The iPhone Be Updated?

There are some basic stability issues with the iPhone that would seem
to be high priority for a software update. It's curious as to why
Apple has not quickly taken care of these issues.

Is it possible they are putting together one large update instead of
several minor ones? Are they even considering adding a major feature
like iChat and need extra quality testing time?

It's likely that Apple wants to minimize the annoyance of constant
updates, but seeing how most current iPhone users are early adopters,
that would be a nonfactor. In fact, I wouldn't mind seeing some of
these issues picked off one by one while my interest in the device is
high. It's almost starting to feel like the phone has been abandoned.
