iPod touch 2nd gen

The second generation iPod Touch featured a new tapered chrome back with Nike+ functionality, volume buttons, and built-in speaker added, It was unveiled on September 9, 2008, at the "Let's Rock" keynote presentation. iPhone OS 2.0 and App Store access standard. Bluetooth support added but not made active until iPhone OS 3.0, which requires an upgrade fee. Support for external microphone and remote added. The 8 GB model was re-introduced alongside the 3rd generation iPod Touch in September 2009, and included the newer iPhone OS 3.1. iOS 4 was released for free for second generation iPod Touch models June 21, 2010, but included a limited selection of features. Future iOS software updates no longer supported (As of iOS 4.2.1). The 2nd generation also comes with the chrome frame seen on the iPhone 3G, making the two almost identical when viewed from the front. However, there are some notable differences, as there is no speaker above the screen, no silent/ringer switch, the back is metal, and the sleep/wake button is on the other side.
