While it is connected, simply hold down the home and power button together for about 10 seconds, then release the power button while continuing to hold the home button.A few seconds later i Tunes should detect your i Phone, Select the "Summary" tab.

According to Apple, the oldest i Phone model to get i OS 8 will be the i Phone 4s (the oldest i Pad will be the i Pad 2).However, the company became the subject of a lawsuit from an unsatisfied customer over the issues.Around the same time, the release of i Phone 4 and its subsequent antenna problems made Apple focus on unsuccessfully attempting to patch the issues with software updates.The company sold 1.7m handsets in the first three days, which according to Jobs made it the most successful product launch in Apple's history to that point.For Apple, cutting the ageing phone loose makes sense - one less piece of hardware to worry about when testing software, plus this should kick off the upgrade cycle again for i Phone 4 owners who don't want to be left out.
