I tried a while back to use Foxfi (wifi) when I got ICS but it didn't work as most of you already know because you tried too. So I bought a bluetooth dongle with the hopes of using that to tether. Well, I got my laptop connected to my phone but I saw this warning about calling customer service to tether. Foxfi does have an option to hide the tether but it only works with wifi.
However all was not lost. As usual, thanks to the awesome members in here I found Pdanet. It works great. I don't mind usb tethering so this is perfect. It has an option to hide the tether too. So if you're looking for a tethering app try Pdanet. There are also drivers you have to download onto your computer but the link for them comes with the app. Happy Tethering everyone!!!
