How to close apps on my iPhone 3G
Hi guys,
I've been looking everywhere for this.
All I can get is people saying to press the home button twice.
But it DOES NOT WORK on my iPhone 3G, iOS 4.2.1.
So now it's slow, freezing occasionnaly et MAPS... my god... I can't use it anymore... I press a key (a letter) and it takes over 2 minutes for it to appear.
But anyway, could someone help me out ?
1) How to close apps on iPhone 3G ?
2) How to make it less slow ??
