I just purchased a M70007T tablet running Android 2.2 from Geeks.Com. It's my first tablet and my first exposure to Android. I'm a mainframe programmer, and I consider myself at least somewhat technological, but I can't figure this out. I'm trying to connect the tablet to my wifi at home, and I have to key in the password. How do I get a keyboard to appear on the screen so I can do so? Thanks.
