When I was using the ver 1.xx firmware, I could make internet calls on E61i through GPRS connection. But when I update the firmware to ver 3.xx, I can't do this anymore. It says no wlan signal, and no internet call icon showed on the top even through it has been connected to the sip server. There is no problem making internet calls through WLAN access point. Does anyone have the same problem? Any tips?
