I am fairly new to Android and to the Galaxy Tab also. With rooting... does that also Unlock the T-Mobile version to allow you to use an AT&T SIM card and their network? On another subject. I remember when I was messing around with the 1st Motorola Droid phone... there was a way to display a stop currently running programs/apps. Not sure if it was built into the OS or an app. Is there one on the Galaxy Tab or do I need to download one from the marketplace?
