Apple has received criticism for charging iPod Touch owners for major updates of iOS that iPhone owners can obtain at no charge, as well as excluding certain features from the iPod Touch software that are included in the iPhone.[12][13] Apple has said that they can add features for free to the iPhone because the revenue from it is accounted for on a subscription basis under accounting rules, rather than as a one time payment.[14] At WWDC in June 2010, Jobs announced that Apple had found a way to make subsequent OS upgrades available free to iPod Touch owners. However, iOS 4.0 and onwards isn't available for the first generation iPod touch and some features are only available for the 32GB and 64GB third generation iPod touches released in September 2009 and the fourth generation iPod touches in 2010.
The iPod Touch and the iPhone, a smartphone by Apple Inc., share the same hardware platform and run the same iOS operating system. The iPod Touch lacks some of the iPhone's features and associated apps, such as access to cellular networks (and speaker on older models). Also, the hold button is on the opposite side (until the iPod touch 4th generation). As a result, the iPod Touch is slimmer and lighter than the iPhone. Steve Jobs once referred to the iPod Touch as training wheels for the iPhone .[15]
Starting with the second generation, iPod Touch can only be charged from the 5V pin of the dock connector while most previous iPod models (including the original iPod Touch) could also be charged from the 12V pin for FireWire power.[18] This change dropped support for charging in vehicles equipped with a FireWire-based iPod connection. Most aftermarket manufacturers of such equipment offer cables and/or adapters which convert the vehicle's 12- V to 5on. Most aftermarket manufacturers of such equipment offer cables and/or adapters which convert the vehicle's 12- V to 5< V.
The only official way to obtain third-party applications for the iPod Touch is Apple's App Store, which is a branch of iTunes Store. The App Store application, available in all versions of iOS from 2.0 onwards, allows users to browse and download applications from a single online repository (hosted by Apple) with the iTunes Store. To develop such software, a software development kit (SDK) was officially announced on March 6, 2008, at an Apple Town Hall meeting.[20] The iPhone SDK allows developers to make applications for the iPhone and iPod Touch after paying a fee to join the development team. The developer can then set the price for the applications they develop and will receive 70% of money earned. The developer can also opt to release the application for free and will not pay any additional costs.
