Just downloaded the skype app for my iphone and used the app. then i lost my tmobile service. seems to have crashed the ultrasnow lock. All my cellular data is gone in the network settings on the iphone too. I tried reinstalling the ultrasnow but no luck with anything. Im using jailbroken iphone 3gs 4.1 BB 06.15.00. Any advice? Appreciate all the help i can get.
