GSM losing a network each 20-30 second

It does not help :) Even with terminal commands, Powering and unpowering,
GSM modem absolutely not responding. Yesterday I did flash my neo with
(http://www.qtopia.net/modules/mydownloads/singlefile.php?lid=50) and it
works almost fine! :) But on battery time is only 5-7 hours (Not
suspending)... If suspend mode enabled, to re-enable GSM after resume I have
to restart neo, no other action can back GSM to work.
Also when I standing far away from GSM antenna - accumulator (or something
else) become worm, I can sense it even by touching LCD or Neo back cover! Is
it normal ? :)

Thanks a lot for providing the network information with us. :) If you'd
like to re-register to GSM network, you may either from GUI or terminal
command as below:
1. GUI: click the GSM signal antenna indicator from main screen, choose
Power-Up GSM antenna, and then choose Power-Down GSM antenna.
2. terminal: http://wiki.openmoko.org/wiki/Gsmd#Usage_of_shell_mode
