hi everyone, Of recent, I am experiencing phases of no wireless signal for my Atrix 2, purchased in Jan 2012. I am on AT-T network and the customer service often tells me I am in one of their best coverage area. I don't get missed calls, but only voicemessages. This device had better signal earlier, but not these days. Does anyone have any tips for me? The solution AT-T gave me is to exchange my device for another "like" device. Thanks!
