iPhone 3GS looks nearly identical to the iPhone 3G that preceded it. The only visual difference is that the markings on the back of the phone are printed with a heavier weight font and a more reflective silver ink than the iPhone 3G.
The iPhone 3GS has many feature changes. The screen added a new “oleophobic” oil repellent coating. The “S” added to the name might refer to its increased speed: the processor increased from 412 MHz to 600 MHz, the onboard RAM doubled to 256MB, and the cellular network speed increased to 7.2 Mbps. The camera was also upgraded to 3.0 megapixel with VGA video recording at 30 FPS, as well as autofocus, macro, and white balance support, a tap to focus feature, and the ability to trim videos. The iPhone 3GS also added a compass.
Several new accessibility features were added, including VoiceOver, voice control, integrated Nike+iPod support, and an inline remote on the headphone cable, all features that had been previously added to iPod shuffle Generation 3.
The iPod shuffle Generation 3 was released in two stages. The initial release came in black and silver, and a later release added blue, green, pink, and an all-stainless-steel “Special Edition.”
The design of the iPod shuffle Generation 3 was considered somewhat controversial because it had no external screen or controls. The three controls—volume up, volume down, and “action”—are all on the earphone cable. VoiceOver technology, accessed using the “action” control, spoke song information.
This example is an unopened stainless steel Special Edition. It was only offered in a 4 GB capacity, and was only available at Apple Stores.
The iPod nano Generation 6 was a major design change from previous iPod nano models. This iPod nano came in silver, graphite, blue, green, orange, pink, and (PRODUCT) RED Special Edition. Its design was a square aluminum and glass case with a clip on the back and a 1.54-inch Multitouch screen.
Although its interface looks similar to iOS, it cannot run iOS applications or games compatible with previous iPod models. Its features include a pedometer, FM radio with live pause, Nike+iPod functions, VoiceOver, and Shake to Shuffle.
The iPod shuffle Generation 4 is a rare example of Apple reversing a design theme and going back to a design closer to a previous design, while still improving upon it. The iPod shuffle Generation 4 has a design similar to the Generation 2 iPod shuffle, but it is smaller and adds a “VoiceOver” feature that reads the name of songs, artists, and playlists out loud. While the Generation 3 iPod shuffle had no controls on the iPod device, the Generation 4 added the clickable ring buttons back to the iPod.
The iPod shuffle Generation 4 was available in five colors: silver (with a black button ring); and blue, green, orange, and pink (with a white button ring). All models have 2 GB of storage, or up to 500 songs.
