Hey guys know no one knows 100% for sure how Att is catching people tethering but it sucks that they take away your unlimited data if you tether Most of the people using MiWi have been caught and because of this PDAnet has come out with an update to their tethering app that claims to "hide tethering usage". It uses different levels of security to do this (1 and 2) and seems to try and fool Att into thinking your computer is an iPhone while you tether. The only problem? There is no way for an Att person to see if PDAnet is actually working and fooling Att to think your computer is an iPhone. This is because when they take away your unlimited and upgrade you to the 4gb data pro plan it doesn't tell you if you are using tethering data or regular iPhone data. The solution? If a Verizon iPhone owner who has unlimited data purchases the $20/mo 2gb tethering plan option, they keep their unlimited data and have a separate bucket of tether data to draw from. This means that if a Verizon owner with the 2gb tethering option uses PDAnet "Level II" protection to tether and can tell us Att owners if it draws from their 2gb tethering data bucket or if PDAnet actually fools Verizon to think that you aren't tethering (if it only uses your unlimited). If anyone knows a Verizon iPhone owner that already has the tethering feature or is willing to do this it would be greatly appreciated by myself and the community Eventually Verizon is going to kill off unlimited data as well and if they do that then they will target Verizon unlimited data owners as well. If you do this and PDAnet works you will also be helping yourself down the line avoid Verizon switching your unlimited plan in the future once it's not available. The steps: - Verizon iPhone owner w/ unlimited data - Purchase the 2gb tethering add on - Use PDAnet to tether using level 2 protection - See if it used your unlimited data or your 2gb tethering data Thanks again for your help.
