I can't say I paid attention to the OS version when I did this, put I know out of the box the "Wireless Upgrade" options wasn't there then when I intalled the Desktop Manager it told me there was an "update", which I installed and the "Wireless Upgrade" appeared. I'm brand new to BlackBerry so I didn't check the OS versions but assumed if an update was available I ought to do it. Now on 4.0.7.65 & platform 4.0.0.76
