Verizon gave me a website to download the Desktop Manager, because I do not have it , but the Desktop manager version is 4.7 where as my Pearl is v4.5.0.77, what should I do?
You're confusing things - Desktop Manager has it's own versions, nothing to do with the OS version of the phone. DM version 4.7 causes a lot of problems with bb's except for the newest ones, 4.6 without Media Manager (it's a memory hog and doesn't work that well) is what's recommended lately.
I think I need that website as well as my phone does not have everything I need on it-is there anyway you can share the site Verizon gave you for the desktop manager?
