you don't need to suspend - just plug usb in and replace battery. iirc
this should do no harm to neo... i do this all the time. i am even
thinking of a tiny small usb battery (20sec of runtime is sufficient)
for quick battery replacement...
of course, gsm is powered directly so it will loose power... for the
time of replacement
