The app just let's you access the forum. Kind of like Tapatalk. You've been-----\/\/\/\-----Thunderstruck!!! By a rooted ADR6400L
Is this the phone you are referring too? http://www.wireless.att.com/cell-ph...re+(TM)+4G*&q_sku=sku5100284#fbid=hdhfJUxj-ak I've searched AT&T's website and that is all that would come up, also on the web. Usually the better tethering apps require you to be rooted. Before doing so yourself I suggest you read up on it in various forums. Like was already suggested try XDA developers, look for your phone then click on development. Under that they should have a stickey with all the guides you would need to get your phone rooted and a custom rom installed.
LMAOoooooff at getting a virus from a blck market that's what anti virus is for lookout and avg some people have no clue what they are talking about also the people who run the black market notify you of the bad apps learn about android phones before you talk about a virus rooting your phone brings up the virus notification when u run it lol
Regardless of whether you can get a virus from them or not, why do you insist on stealing from somebody's hard work. You can't fork out a cheap 99 cents to support somebody's programming work that you obviously want to use? I will continue to support great developers and I hope most others do. Otherwise, developers won't want to develop on the Android platform.
There are apps on the market place that will allow you to root your phone the easiest way is 1 click root with cwm ad also download odin and all the tar files u will need in case u need to flash back to stock before taking in your phone for a replacement
