Not sure if anyone else has reported this but it has become commonplace since upgrading to 2.2.1 I get marginal service at my house, usually 2-3 bars, however when my battery gets low my phone constantly "loses" the signal, usually ocurring after erratic battery readings, such as the indicator will say its still in the green however ill look over and get the black screen with the battery and the icons to charge it, when i try to access my phone itll hang for a second then drop service. Am I crazy or alone here?
