I have a rooted Viewsonic G-Tablet running Cyanogenmod 7 (Android 2.3) which is Wifi only, and a rooted G1 running Cyanogenmod 6 (Android 2.2). When I want to use 3G on my tablet, I merely press a button on my phone to turn it into a wireless access point, and then connect my tablet to that. I buy T-Mobile UK's 6 month data booster for £20 once every 6 months. It gives me 1GB of data each month for 6 months. Effectively they give me 1GB/month of 3G for £3.33 which is about 5USD.

Maybe you didn't read the article, but what I actually did was to help secure a website and then help inform people about risks they may not be aware of. At no point did I commit any crime, spread any malware, or any adware. Moron.
