I rooted my Droid X, the main reason was so I could make my Nook Wi-Fi able to download books over 3G whenever I had my phone
Apparently the Droid X only did Ad-Hoc with the Free apps that were out there, and the Nook can't see Ad-Hoc networks.
Well....I found a direct hack to the NVM that allowed me to use the 3G HotSpot that came on the phone without charging me the $20-$30 for the mobile hotspot feature. You can test this because when you open a web browser it points you to verizon.com or if you didn't pay, ask you to pay. Kind of like ATT Wifi
With the hack, it just takes you to your default homepage. So viola! LOL, pretty excited. The only reason I want to tether is for the Nook in the first place LOL.
