I am completely untechnical with this Motorola Droid X and don't know anything about rooting, (at least not the way y'all mean it here!).
However, with a $6 Bluetooth usb dongle I used to use with a previous phone, I just 'wirelessly tethered' my laptop and Droid and got online quickly and easily using the built in Bluetooth Personal Area Networking and Dial up Networking. My Bluetooth dongle came with BlueSoleil software which isn't exactly intuitive but once set up is easy to use and connect with the phone. I'd used it previously with a Treo 650 and a Treo Pro, (both also Alltel/Verizon), and now found it useable with my Droid X.
It wasn't blazingly fast but certainly adequate for my needs. I was able to check email, watch a YouTube video, do an online banking transaction, etc.
For my limited use this will work fine and may for others, too. As I recall, I bought the Bluetooth USB dongle at CompUSA.
I hope that's helpful.
