The iPod touch 3rd Generation (Late 2009) models -- please note that this model does not have 3G networking support -- were marketed with an increased emphasis on gaming rather than the "iPhone without a phone" pitch provided by previous iPod touch models. Nevertheless, they offer much of the same functionality of the iPhone 3GS, minus the "phone", mobile phone networking (3G/EDGE), A-GPS, digital compass, and integrated camera.

Although they were initially sold effectively as a single lineup with 8 GB, 32 GB, and 64 GB of storage, the 8 GB model is different in some respects. Most notably, the 32 GB and 64 GB models are the same externally as the iPod touch 2nd Generation but have innards more in common with the iPhone 3GS with advertised "50% faster performance" and OpenGL ES 2.0 support for better graphics performance (courtesy of the same 800 MHz Samsung ARM processor that powers the iPhone 3GS). In addition, the 32 GB and 64 GB configurations fully support iOS 4 and iOS 5, whereas the 8 GB configuration does not.

Like the iPod touch 2nd Generation, the iPod touch 3rd Generation models feature the same "multi-touch" sensitive 3.5" display with 320x480 resolution, accelerometer, ambient light sensor, and support for 802.11b/g (hardware-capable of 802.11n as well).

In addition to superior performance when compared to their predecessors, the 32 GB and 64 GB configurations also added Voice Control capability for voice navigation and a "VoiceOver" screen reader for the visually impared and shipped with the same "Earphones with Remote and Mic" as the iPhone 3GS.

Battery life is an Apple-estimated 30 hours for music playback and 6 hours for video.
