What is iPod Touch/iTouch??

The iPod Touch or so called iTouch is a portable media player, personal digital assistant, and Wi-Fi mobile platform designed and marketed by Apple Inc. Basically it's nothing much just like an iPhone without a phone calling function.



The iPod Touch has a slim rectangular shape with rounded edges, with a glass touchscreen display covering most of the top surface and a physical home button off the touchscreen. The display functions similarly to the multi-touch trackpad as implemented in Apple's current line of laptop computers.



The home screen has a list of icons for the available applications. All iPod Touch models include such applications as Music, Videos, and Photos (collectively duplicating the standard functions of the iPod Classic), iTunes (providing access to the Wi-Fi Music Store), Safari, YouTube, Calendar, Contacts, Clock, Calculator, and Settings. Later models added Mail (accessing POP/IMAP/SMTP e-mail), Maps, Stocks, Notes, and Weather, which could also be added to the earlier models with the purchase of a software upgrade. The user can add direct links to Web sites, called "Web Clips", to the home screen. All iPod Touch models are equipped with Wi-Fi 802.11b/g.

Comparisons to the iPhone and model comparisons

The iPod Touch and the iPhone, a smartphone by Apple, share the same hardware platform and run the same iPhone OS operating system. The iPod Touch lacks some of the iPhone's features such as access to a phone network and built-in camera and microphone; as a result, the iPod Touch is slimmer and lighter than the iPhone.



The second generation iPod Touch has an external volume switch and a built-in speaker like the iPhone. The second 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. The second generation also supports audio input when a headphone or earphone with microphone capabilities is plugged into the audio output (headphone) jack. The iPod Touch 2.0 Software Update supports WPA2 Enterprise with 802.1X authentication. The iPhone OS 3.0 update unlocked Bluetooth capability on the second generation iPod Touch, as the included Wi-Fi chip (Broadcom BCM4325) has Bluetooth support.


Second generation iPod Touches are said to have a yellower cast/tint to the display, as compared to the iPhone or the original iPod Touch. The applications processor inside the second generation iPod Touch runs slightly faster than the processor inside the iPhone 3G, but slower than the iPhone 3GS.
