OK, so I got it for $40 on craigslist so I had an expendable tablet to play with before I pull the trigger on a big 10". Now I need to find out how do do some things to it to make it usable. 1: It's running 1.7.4 and I need to upgrade it to 2.1. I have Win7 64-bit if that makes a difference. 2: The WiFi isn't working with WEP but I think this is a ROM issue (I hope) that should be fized once I upgrade it. 3: How do I even find out (since it'll be asked) what make/model/firmware/etc. this thing is. In the About Device it says: Model Number: generic Firmware Version: 1.6 Kernel version: 2.6.29-00236-g4f8dbbb-dirty Build number: 1.7.4 4: How do I install programs to/from the SD card? I want to put the Google market and apps on here. Thanks all! Please help!
