The the iPhone and iPod touch 2.2 Software Update has been out for about 5 days now. It is the last iPhone/iPod touch update for 2008. The Software Update adds new Features to the iPhone and iPod touch like:
Google Street View (iPhone only)
Download Podcasts in iTunes app
Auto-Correction On and Off Setting
Rate apps before deleting them
More Language Support
The update is well worth the download. Since it adds all these features and is faster and more stable. But 2.x Firmware still makes 1st-Generation hardware (iPod touch 1G and iPhone) a little laggy. The update is a most have for any iPod touch 1G, 2G, iPhone or 3G owner.
