iphone issues :(

Hi all,

Im new to the iphone but im having an issue that occurs every week.

Basically my phone will start going all funny.. for example, i cant swipe to unlock the screen will look likes its frozen for a bit so ill have to press the power button to kinda wake up back up properly then the swipe to unlock window will come back. Then all the apps run a bit strange or slow so I'll turn it off to give a refresh but it takes almost forever to turn back on then once im in it will say activating iphone, then actvation complete.

After that the phone will run normally again but the downloaded apps dont work they open for 1/2 second and close again.

I have to fix this by reloading everything in itunes all over again.

I usually charge my iphone on my work computer or on my alu macbook at home at night when the lids closed and it has to wake up to charge it. The macbook is the computer i sync with.

Any ideas?


Thankyou
Brendan
