A lot of you were able to root your Bionic, but found that you couldn’t WiFi tether. It looks like Verizon and Motorola have stepped up their efforts in preventing your from tethering, but thanks to xda member ddv2005, you can now freely tether away.
From the post:
I found way to enable Hotspot without Verizon Provisioning. I used SQLLite Editor to modify settings.db for “Settings Storage” application ( com.motorola.android.providers.settings ). Set entitlement_check to 0 and reboot the phone.
