Thanks for the link. I downloaded and installed that Tmobile OS update on both of my 8320s and they are working great so far. I have installed new 4.5 themes as well.
It is good to know that the carriers released new OS updates. Far different from my Motorola phones of the past (v300, v3 RAZR) that I had to manually update their OS through some pretty sketchy software
Blackberry Desktop Messenger makes it pretty easy. I do wish there was a way to manually navigate the Blackberry files with the ability to delete any unused items to free up storage space and potentially make it a bit faster. I used to do this with my Motorola phones and it worked really well. I would also like the ability to remove programs that the DM cannot remove.
