I tried to install it, but after running the EXE, I started up my Desktop Manager and synched my BB 8310, and nothing changed. Still running Op system 4.2.2.170
When I run the install file, my desktop manager under Help, device software, showed 4.2 and 4.5, but did not put 4.5 on my Blackberry. How do I get it to install? When I upgraded to 4.2.2.170, I had no problems.
I use AT&T, is that the problem?
