Download from here : http://storagehot.com/Kasey90612/iphone Today we got to see Apple update the iOS 4.0 Firmware to 4.0.1. This is the update that Steve Jobs as talking about. Here we have the signal bars a bit bigger and more accurate. Ive been hearing of people having problems with the signal not going past 3. If anyone is not Jailbreaking and has updated, have you experienced any problems?
