It's a big news day for the iPhone. The 2.0 Firmware for all iPhones was released (sadly none for the iPod touch yet), the iTunes Music Store has iPhone applications for sale and, the first 3G iPhone take-apart photos have hit the net!

The 2.0 iPhone firmware update allows the installation of 3rd party applications on the iPhone and comes with some other minor updates, such as 3D buildings in Google Maps. Get the details on downloading and installing the free update here.

Once your iPhone is updated, head over to the iTunes App Store, to check out all of the cool games, communication and productivity software! Apps of interest include Smug Shot (a kind of Photo Booth that uses the iPhone's camera), Enigmo (an amazing 3D puzzle game), and Type Pad (a mobile blogging app).

If you don't yet have an iPhone, or you want to see how the new 3G iPhone differs from yours, check out the first 3G iPhone take apart in New Zealand (yes these guys flew halfway around the world to be the first to crack one open)!
