HI. I ain't too smart and am not a technical kinda guy, so please be gentle with me.... I have a 9530 I bought unlocked in January and connected to T-Mobile. Very few problems. I had not updated the device until today. Data works great and it runs so much faster and smoothly it is wonderful. BUT - I have no voice service now. I changed the setting to GSM/UTMA and am now seeing the "EDGE" setting. But I can't dail in or out - get an error saying "No Circuit/Channel Available". I have plenty of bars and have never seen that before. Please help. Thanks.
