i'm using ultrasn0w 0.8 on a 3g device. sometimes i see that my internet using the edge does not work. so weather update fails and all other internet useage fails. then on its own it works. there is no network issue because my brother's iphone on 2.2 & same network has no issues.

is this related to 0.8 ultrasn0w in any way? what's causing this erratic behaviour on edge usage?

please need advice on this. thanks
