Apple will introduce new versions of iOS and OS X at its annual developer's conference.
iPod Nano and iPod Touch Dimensions Revealed?
The new iPod Nano resembles circulating rumors, though the front display does not appear to be as curved as previously depicted.
The new iPod Touch will be receiving a tapered design much like the new iPhone 3G. The new case appears to be slightly thicker than the existing iPod Touch and also reveals physical volume controls which are absent on the current iPod Touch.
Case manufacturer XSKN is already selling cases for the 4th Generation nano which match the design and does suggest a very rounded design.
Apple is expected to release these new iPods on September 9th, 2008.
