Yes, for an additional $20-30/month. Foxfi is free and was working on DroidX. I believe you can get free mobile hotspot with the new share plans, but I have an older 2GB/mo plan.
I'm not passing judgment of any kind on this topic.....but.....
With the unlimited data plans, if you wish to tether or use your phone for a hotspot you are required by your terms of service to pay Verizon $20 a month for doing THAT. Yes...there are apps that will allow you to do it without paying, but if you get caught....it's considered 'theft of service" and you can get your service cut and your account closed.
The new share everything plans do not required payment of additional fees for tethering or using your phone as a hotspot. My Razr M (like my D2G also) have hotspot capability built in and there is no need to run an app to create a hotspot. The only real reason to do so (on this phone) would be to circumvent your terms of service and get out of paying any required fees.
