Hey guys, I've been a long time lurker on these forums, and everybody has given great advice. I have a couple of questions: I was wondering if there was a way (even through an app) to automatically turn cellular data off when wifi is in use so that the battery is not drained when wifi is on? Would you still be able to make phone calls and send text messages with wifi only? Also, if 4G is not in your city, does the atrix still look for 4G? If so, can you stop that? Thanks in advance.
