I think you need to be rooted to use barnacle...PDANet lets you use bluetooth and it's free, that's why I used when testing bluetooth tether. A little confusing to set up though.
Yea I use pdanet for usb/bluetooth tethering...usb is easy just follow the instructions on the pdanet website. Bluetooth instructions are there too but it is a little harder you basically need to make the connection via your computer (which must have bluetooth) and create it under dial up networking in the droid X's bluetooth services.
And rooting is something that gives you superuser access to your phone so you can change things you couldn't otherwise...Once you root you can install wifi tethering apps that are free such as barnacle and not pay verizon the $20 monthly ripoff charges. Just google "droid x one click root" and follow the instructions.
And no PDANet and its bluetooth/usb tethering don't require root. That is why I am wondering if Wifi tethering is faster than usb/bluetooth because it's the only thing Verizon charges for.
Well I have easy tether on my phone for a USB connection and it works good... Id like a bluetooth connection tho, i have the PDAnet app downloaded on my phone. I see a button that says Enable bluetooth DUN i click it and it says Bluetooth DUN service is running. You may Need to Pair your phone and your computer (agian) before connecting.... and thats as far as i can get
You don't need an app to use bluetooth to get online. Just set up your pc/laptop to recognize your phone via BT, then connect to your Droid via access point in the "Devices and Printers" folder. That's it.
