Hi, here's my experiences on Windows 7 Ultimate 32-bit OS's, running MM3 and MM4.
iDevices with OS5? iPod Touch version 4.2.1, manually managed. Not visible in MM3, always Scanning in MM4. Tried downgrading iTunes, no difference - not sure if the downgrade was required, or completed properly..
I can't retrieve music from iPod Touch / iPhone devices. Assume it's an OS5 issue, as this appears to be intermittent.
iDevices OS version - how can this be identified? I go (device) settings > about > general.
Can't see playlists or other content. Installed the itunes plugin device, appears to work to transfer media TO the device, "via" iTunes... is it supposed to enable transfer of media FROM the device via MM also? This is not possible for me right now...
Glad to provide any other data. Thanks for all the support monkeys
