I have an 8707g that was purchased directly from RIM and has T-Mobile as the carrier. I wiped the device software using the javaloader but now I can't reload it. I've downloaded the device software from Blackberry but when I run the application loader all I see is a messeage stating "The Blackberry Desktop Software does not have Blackberry Device Software for the device you have connected to the computer". The Blackberry Desktop Software is ver 4.2.2 and the device software is ver 4.1.0.

Did you install the Handheld OS installation package on your computer? (the 4.1.0 version)

Yes, I've installed the Blackberry v4.1.0 for the 8707 Seriw Wireless Handheld and I've changed the desktop software to ver 4.1 but still get the same issue.
