WiFi Tether?

view story

http://forums.androidcentral.com – I am stock ics unrooted on razr maxx hd. Foxfi used to work but now my laptop restarts every time i try to connect to foxfi. I tried to connect to foxfi bluetooth but i couldn't get to the page in which bluetooth connects to internet on my laptop. Is there a free wifi tether app for unrooted razr maxx hd that still works? I don't mind paying for an app but i don't want to pay only to find it doesn't work when we get the jb update. I am on verizon wireless and do not pay for their wifi tether and i am on a granfathered unlimited data plan. I read one guy got in trouble for using pda (HowTos)
