im running minimoto.
early morning yesterday,i had to call 911 for an accident and after a few mins it said "no gsm/umts" and switched to global,this was probably the worst time to have phone issues.
the signal bars went away and there was the triangle symbol,after a minute,the bars came back and it seemed to be in global mode and i recalled 911,after about 2 minutes,same issue.
just want to put this out there,worst time for phone problems is when you need to call for an ambulance and people are hurt.
is it just the rom or the build.prop? obviously this one is hard to test out as calling 911 for no reason is a crime.
