I just purchased unlocked Vodafone BB Storm 9500.
Current OS version is 4.7.0.181.
But in application loader there is an option to upgrade on 5.0.0.402 version.
After clicking next on desktop manager, message appears saying that I need active Blackberry service subscription.
How to upgrade my OS?
Also I would like to hear add advantages of new version of OS against current one on my Storm 9500
