If you have an enterprise activated device and you want to update the handheld software, you might bump into this little error

You cannot update your software using this system as your device is currently activated on BlackBerry Enterprise Server or BlackBerry Professional Software. Please contact your administrator for updates. Or check for updates from your carrier service provider

you have two choices
1. remove the it policy on the handheld
2. edit the it policy on the BES to allow non enterprise upgrade (this does lead to reactivation)

I opted for option 2 since i manage our BES server. those of you who opt for option 1 need to continue googling

So for option two.
1. we edit the policy on bes Refer to instructions
2. Roll the IT policy back out to the device from the bes manager
3. Reboot the device
4. download the latest handheld firmware to your pc one size fits all
5. install the latest firmware package on your pc
6. remove the vendor.xml (C:\Program Files\Common Files\Research In Motion\AppLoader)
7. run the loader.exe and upgrade the devices firmware (C:\Program Files\Common Files\Research In Motion\AppLoader)

Finally
8. reactivate the device to rejoin it to the bes

and your done
