My house has poor reception. Yesterday, I go to make a call, and all I get is "Network busy." 0) I haven't received the OTA update yet. 1) Network is in the low 80's db. 2) I can receive calls and hold a conversation. 3) I get 3G service (1 bar) 4) I can make calls from my wife's ENVY touch right next to it. Does it really need that much stronger of a signal to dial out than hold a conversation?
