If you have Verizon and are willing to pay for it (I believe it's another $30/month on top of your data plan?) you don't even have to jailbreak. However, I entirely understand if $60 every month is too much; I rooted my Android phone to use it as a hotspot without paying a fee up until I updated my firmware.

Me, too. Being able to tether and not pay extra for it is the only reason I would jailbreak.
