Skype 2.0 for iPhone has finally arrived, bringing with it the 3G calling that's been promised for months and months. But get your calls in quick—there will be a "small monthly fee" for Skype-to-Skype calls after August.

That's an unpleasant surprise, definitely, but at least for the summer you'll get the 3G Skype-to-Skype action you might've forgotten you were waiting for. Here's the full rundown of what's new:

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.
