I experience intermittent data service with my Koodo LG P970G. It happens on a daily basis in strong (5 bars) and weak signal areas, in both urban areas and rural areas, across Ontario. This was an issue on Android version 2.3 and it continues after the update to version 4.0. When the data service stops working, the "H" icon remains on display, and the up arrow flashes to indicate data being sent, but the down arrow does not flash to indicate data reception, and of course after a short time the browser or app in use returns a network timeout error. The service usually returns in a few minutes. At the same time, I have never experienced a dropped call that could not be explained (such as travelling through an area with weak service), so I would presume the hardware to access the network is good.
