I have had the hero for over 1 year now on Orange. Works perfectly for me and have had no problems using the mobile network (Edge) in my area over that time except for the last 2 days. I have a full mobile signal of 4 bars but my mobile network connection will not work. I enable the mobile connection and I dont get the E (Edge) symbol that normally sits beside the signal bars and this is still with a full signal as indicated by 4 bars. I can make and receive calls and texts but no network connectivity. It does connect on the odd occasion for about a minute and then drops again. The mobile signal only fluctuates slightly between full and 3 bars. Anyone else had this issue recently and solved the problem ?
