I just got BlackBerry 8700g. It's from Italy and I use it in Serbia. It's unlocked, so it works with our network.
The OS is v4.1.0.377 (Platform 2.0.0.152)
I downloaded Desktop Manager, but it works only with backup and restore. When I try Roxio manager to transfer photos or sound, it says that device is not connected?! :(
I really don't know anything about BlackBerries, I'm using it for a first time, so I really need help... a lot of help...
Also, I saw you're talking about new OS, how to instal it?
