I want to install the Blackberry Messanger for the 8320 but when I attempt to download it, it says:

"Unsupported Device
Sorry, your device does not meet the system requirements that are needed to support BlackBerry Messenger for Software Versions 4.0 and 4.1."

I'm not sure what Software Versions they're referring to. My Options->About reads v4.2.2.180 (Platform 2.5.0.36), so I'm guessing that's the version they're referring to.

How do I bypass this issue? Thanks.

PS: I'm new to the Blackberry world
