Losing signal regularly?

[EpicKN]

Just jailbroke+unlocked my iphone for use with tmobile.
Ever since, the signal quality has been full bars, but every few minutes it will go to 0, then a few seconds later back up to full.
Anything I can fix?

I get it sometimes. I have to reboot my phone 2-3 times before the signal behaves. Once I get that going I make sure the phone never shuts off It's obnoxious though.

I have been having issues with that. There has to be a connection issue between the phoen and the tower. Maybe there is a hack for it? i know when i get edge going- its even more prissy.
Anyone with some insight on this?

Same here... I think it may have something to do with UltraSn0w... but I dunno.

Back with 2.2.1 + yellowsn0w I had a similar issue where I would lose signal more often. Though after upgrading to 3.0 + ultrasn0w it is much better now. Did you use redsn0w or a custom FW from pwnage tool?
