Home button on iPhone4 gets stuck. Any advice?

[TimeForCake]

It seems to have stopped responding and only works every now and then which is really annoying! Have switched it off/ restarted it to no avail.

Any ideas gratefully received.

It's a bug. Very annoying. Click it twice which shows a bar of all open apps along the bottom. You will likely find there are loads "open" despite restarting etc. Touch one til they all wobble and then close them using the "minus" sign in top left corner. You have to do this regularly but for some reason it seems to work.

Thanks SkiBum, will try that. It's driving me mad!
