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....

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...
