hi
i just recentely buy Iphone 4 and when i try to connect it to the pc it being detect by Itunes but not being dectec by the pc itself (means that if i go to "Computer" i can't see the Iphone icon there being detcted as camera... )

the pc do detect the "Apple Iphone something" (sorry not remeber the name) but not show me the icon so i can use it....

and when i disconnect the Iphone off the Devices mangaer pop up from nowhere and tell me that it failed to install USB MT (i just hope i not mistake and it really "MT" because i not sure if i remeber the name right..) and it only happen to me when i dissconect the iphone... ,when it connected to pc the Devices mangaer do nothing till i disconnect it

i try to play a bit with the Devices mangaer but nothing not happening no matter what i done, i try to delete every apple program from the pc, restart ,and delete every reg file and leftover of apple programs... (done clean uninstall in other words)

and when i connect the iphone then it was detected : D ( ARRRYYY!! \(*0*)/ )

but when i reinstall apple programs it become undetected again! (ouch *-*....?)

the iphone do have pics on it, and working great in other pcs... what can i do to fix this problem?
