Hey guys, anybody that uses their phone for tethering, experience any issues with that? Worked great for almost 3 years...until today. Once I connect to my laptop, it doesn't let me do any surfing whatsoever. All I get is a message from Tmobile to upgrade my plan for an extra 14.99 for the tethering option. What happened? It used to be free. Does this have anything to do with the At&t merger? Any help would be appreciated. Thanks!
