Just upgraded my iPhone 4 to iOS 7, as its an old phone and had lots of use the home button is very iffy and rarely works when pressed. I think this is a common problem as its a manufacturing fault. So good news under settings > general > accessibility > assistivetouch > slide the slider to on. This then adds an overlay button onto the screen, which when touched pops up a dialogue button, including a shortcut for the home button amongst many other useful shortcuts. Even works on the lock screen. Basically this means the jailbreak fixes I relied on are no longer needed, and my old iphone still has useful life left in it. Nice one Apple

Every Time an iPhone gets broken this is the first tip I refer to :) It is MUCH easier than opening the phone and replacing parts :D

Yep, I use this on my iPhone 4 running iOS 5.1. Totally burns me that the physical home button doesn't work most of the time! I'd love to see a software button like on Android. Mark

No problems with my iOS 7 iPhone 4S. My mum's iPhone 4 (running iOS 7) is also working fine. Must just be a slight fault with yours. Maybe it broke in a drop or something. I wouldn't worry too much about it, because if it is a software issue, then just wait until the public release of iOS 7 comes out. I'm sure that most people wont have a problem. Also, would you be wanting to come along to the meet on Tuesday? I sent you an email last night.

Hey Gonorthwest, Totally didn't know it that this feature was available in 5.1 - might have save me the effort of jail breaking my iPhone. Live and learn, but still a great feature. Thomas, have just emailed you.
