Re: Blackberry 8820 - OS Update

RIM are releasing new handsets with updated Operatin Systems on them.


This usually means they release updates to the current handsets as well.


4.5 should be available for your 8820 but I will need to be tested by your carrier (T-Mobile) and accepted into support by them.


They will have to go through the same process should they wish to release 4.6.


I would loook at the carriers web site here for more info http://www.t-mobile.com/bbupgrade/

Re: Blackberry 8820 - OS Update

That was awesome, thank you so much.  I just bookmarked that page.


Does that mean I ignore the updates I see on the web and wait for Tmobile to update their OS?  Or can I jump ship and download OS's from other places.

Re: Blackberry 8820 - OS Update


You can jump ship, but don't expect any support from the vendor on an unreleased (in their eyes) OS.

Unless you have pressing need I suggest you wait for the "official release"
