Droid x. I downloaded the sdk. installed several drivers for the x... Yet the connect to phone option in app inventor is constantly greyed out. The phone is on and plugged in with usb debug etc on. The computer recognizes it's plugged in. I'm sure it's a driver issue, but I can't find anything. If I've tried it it doesn't work and if it works it's in a corner of the net hiding.. I'm beginning to hate app inventor and everything computers at the moment. Had an invite since Oct, and have yet to connect my phone. Cool program.
