I believe if you want to upgrade to the 5.0 OS, though, you need to use 5.0 DM. Although you could use apploader instead
Oh and I agree with Matt lol...I was just adding a bit more info
i am rather short and to the point for answers sometimes. Like i want to be able to just type 'no' sometimes without the 10 char crap....its too much work
Mine does that sometimes. Either try disconnecting and then reconnecting the phone or restart the phone and computer. As for more in depth, I'm not that helpful. Maybe the blunt answering machine could help with that. lol
