actually, what we need here is a running program monitoring software... so to see what are the program that using to many resources at one time... well pressing the home button about 6-10 sec may clear running progs... have you tried tat b4? honestly, i dont really feel the diff... what i do is respring or reboot....

It happened to me before. My iTunes can't read the iPhone.I ust reboot both my computer and my iPhone, reconnect the USB cable to the pc and than it just sort of work. I still dunno why it happen.

Well... that seems normal phenomenon mosai... not only iphone and its itunes or its pcsuit/browser... it happened to all other device also especially winmob devices with thier activesnyc respectively... but hell, its not a bugs at all... reconnecting or reboot is always the first autopsy b4 digging more...
