I would like to know how to upgrade my iPad 1 4.2.1 to IOS5 please. I would also like to know if I complete the upgrade, will I have the new cool gestures that replace me having to push the home button all the time? (swipe finger...tap...pinch ECT...) Is this even possible? Is it compilicated to do? What programs/tools do I need to complete the upgrade successfully? ETC... Any input is much appreciated. Thanks.
