“I own the 8310 model BlackBerry… I received an email about upgrading my system from 4.2 to 4.5… Is there a way I can do that from my phone itself?”
The simple answer is, Hopefully in the future! Within the newer OS’s (4.5 and above) there is a wireless update item under Options, but this particular feature has yet to be enabled by any carrier. RIM has implemented the ability but it hasn’t been taken advantage of yet. The only option available right now is to update using you cable and supported OS download. But good things are in store for the future option of updating your Blackberry wirelessly.
Thanks for the question Cast TROY.
