Ever since I upgraded my iPhone 4 to iOS 5 the home button is slow and delayed. When I press home I have to press it very deliberately to get my phone to wake up and I can barely do the double tap to reveal multitasking anymore as it usually doesn't recognize the second tap and just closes out of whatever I'm in . Also when I press the power button to wake it usually is delayed as well. Everything else seams to be fast though. its annoying but I guess manageable...I just want to make sure there isn't anything wrong with my phone or if anyone else has this issue? :O
