Skype and iPhone fans rejoice: Skype 2.0 for iPhone has finally been released. After, like many things in the tech world, being looked forward to and pushed back for a few months, 3G Skype-to Skype calls are now ready to go. This news does not come without a catch though; apparently starting in August there will be a "small monthly fee" for these calls. Here's the list of upgrades and goodies from the iTunes site:

Upgrades / improvements include:

- Call using your 3G connection. Skype-to-Skype calls on 3G are free until at least end of August 2010, after which there will be a small monthly fee (operator charges for data will still apply).

- Near CD-quality sound for Skype-to-Skype calls using wideband audio (SILK codec) on iPhone 3GS and 2nd generation iPod touch.

- Enhanced call quality indicator.

- Improved start-up time.

- Fast access to the dial pad from iPhone home screen.now available.
