Apple's Let's Rock event in San Francisco just came to a close and while the iPod nano was completely refreshed and the touch was tweaked a bit, the iPhone received a firmware update to 2.1.

This firmware was called a "big update" because it addresses several of the issues users have been experiencing. Big fixes being the primary focus, Jobs noted the major areas addressed including battery life, app crashes, back up lag and dropped calls.

But that was it, really. This was truly a music event and Apple stayed on target with their message. Prior to the event, rock music was blasting. But the show ended with a performance by Jack Johnson. Nothing against Jack Johnson, but "rock?" Really?

Stay tuned for a recap of the day's events including the details on the iPod nano and iPod touch updates.
