For those that have not been following along with Apple’s iPhone OS 4 event this morning, or are simply overwhelmed by the amount of information, Apple has now posted an iPhone OS 4 preview page.
The preview page does a fantastic job of summarizing some of the key points of what was revealed this morning at the event. Of particular interest is that not every device (iPhone, iPod Touch) will receive every iPhone OS 4 feature. For example, on the preview page, Apple states:
iPhone OS 4 will work with iPhone 3G, iPhone 3GS, and the second- and third-generation iPod touch this summer, and with iPad in the fall. Not all features are compatible with all devices. For example, multitasking is available only with iPhone 3GS and the third-generation iPod touch (32GB and 64GB models from late 2009).
As was discussed earlier this morning, it would seem that the iPhone 3GS and Third Generation iPod Touch will be able to run the new features with no problems, however the previous generation devices such as the iPhone 3G and Second Generation iPod Touch will have limited access to the new features of iPhone OS 4.0.
As for iPhone 2G and First Generation iPod Touch users, Apple may have ended support for those devices, as there was no mention of them during the iPhone OS 4 preview event.
