I made the stupid mistake to upgrade to 3.2.2 on Ipad and I lost three functions I used a lot previously:
1:Can't use anymore the USB keyboard with the usb-sd card adapter
2:Can't read anymore CFcards with a n USB card reader with the same adapter
3:Can't make a call thru Skype because the Microphone has been disabled
Of course I am not precisely happy with these "upgrades", so I know perfectly well what I am going to do when finally the OS4 is released!!!!!!!!!!!
