Solved: root it and install the CM7 ROM or the latest MIUI ROM. The CM7 one is actually a little more usable (accelorometer and compass sensors working for example). Neither have the proximity or light sensors working, so you’re kinda stuck there. But other than that the pure (enhanced) Google experience on the Fascinate is amazing as I can attest to with my short 3 days with it. Super fast, totally worth the few bugs. Only real sacrifice is the lack of GPS. So long as you don’t depend on it for daily travel, this shouldn’t be a total deal breaker. I can’t confirm myself if its the actual GPS system (I’m assuming) that’s not working so maybe some location based services will still work with the cell network.
Fans of MIUI from other handsets won’t be dissapointed with that ROM either. It looks to run really well (according to the forums) but I’ll be posting a comparison between the two ROMs as soon as my phone gets here. Could be tomorrow, Monday at the latest. Either way, it’s gonna be a long weekend. Hit up the source links to check out the respective forums and download these sweet ROMs yourself.
