would it be possible to get updated hacked version of blackboard 2.0.1
You won't screw anything up, I do believe, because there's nothing that can screw up. The only problems I've seen are the apps just not working on the Fascinate because that's still running 2.1. You'll just need to uninstall the apps if they don't work. I'd suggest you try the market version of the Skype app, however (and not the Skype Mobile as that's Verizon-specific), unless that one doesn't even show up for you.
I tried installing the Skype app on a T-Mobile G2 and when I try making calls (skype users or phone numbers) it doesn't dial, it automatically says "call ended" and exits back to contacts list.
I tried installing the one from the market first but it only makes call via wi-fi and i'm looking for calls via 3g/4g. I then uninstalled the market one and installed the one from the OP (Skype.apk) and I get the error I described.
The one I see in the market says it can call via 3G, so I'm not sure what the problem is. Sorry.
Hopefully X can come through for you.
