OS 4.5 Help
So I just put the 4.5 OS on my phone it is a T-Mobile 8320 when I did that I some how lost my BB messenger does anyone know where I can get it back at I tried mobile.blackberry.com but it says my device aint supported.
Reinstall BB Messenger Via Desktop Manager
To expand a bit, if you installed 4.5 os on your pc then just connect to Desktop Manager (presumablyu you're running DM 4.5 aswell as os4.5 - you should be) and then Install apps and it should bring up a list of all the components of 4.5 os and their status. Just highlight BBM and DM will install it.
~via BB (wap.pinstack.com)~
Be aware that the t-mobile theme does not display the BBM icon. I had to go to Dimension L to get it. You can check to see if it's installed by Options, advanced, applications to see if it's listed in your lineup.
my BB messenger showed up fine...but i made sure it was checked for install when i loaded the new OS...always scroll down and make sure what you want to install is checked and what you don't want isn't...hope this helps
