Mactracker for iPhone and iPod Touch
As Professor Hubert J. Farnsworth would say, "Good news, everyone!" Mactracker has been updated to version 5.0 (we've written about Mactracker before) with new goodies, including
Leopard compatibility
New update engine
iCal integration for tracking the warranty status of the Mac you own
"iTunes Version" compatibility information to iPod models
Plus, data has been added for the MacBook (13-inch Late 2007), iPod classic, iPod touch and more (you'll find the full release notes here). The best part is that iphone.mactracker.ca has been created for use with the iPod Touch and iPhone. Now, all the information you'll need lives online, just a click away.
Mactracker requires Mac OS 10.3.9 or later (desktop version) and is freeware.
