I don't usually start new threads without searching around, but i couldn't find anyone that actually had their plan changed for tethering. they started sending those e-mails in march and it's now may. a few weeks ago i accidentally turned on mywi, but did not connect any devices. 30 minutes later and i got a text from at&t. it simply said "did you know tethering your smartphone requires a tethering plan?" anyways, i updated to 4.3.2 and did not install mywi or tetherme this time. my second question is whether or not it's true that you can't be caught using tetherme because it uses the 'phone' apn so that you remain undetected. i just want some tethering. i don't want to lose my unlimited plan.
