GSM looses connection - Soft Reset needed

[Zippy1970]

My Wizard's (MDA Vario) phone sometimes looses its connection for no apparent reason. It'll have 4 bars of signal and then all of a sudden the bars disappear and you'll see the 4 dots indicating it's looking for a signal. This won't correct itself until you soft reset the device.

Is this a known problem? I tried searching for it, but couldn't find anything.
