I too have the fluctuating 1x bars but (so far at least) have never dropped a call. I am in a relatively weak signal area most of the time -100dBm However my real concern is over 3G dropping in and out. This signal (and frequency) is totally separate, correct? Why is my 3G signal occassionally dropping out? Very annoying when trying to access the Web, etc. Doesn't happen a lot but enough to make me question the radio and if I have a marginal device. Are others seeing this? If I can't get this sorted I'm goign to have to go back to the iPhone. For reference the crappy ATT signal here (frequently -105dBm or worse) never drops 3G. Hope someone can give me a solid answer. Thanks!
