when i go make a phone call it throws me backout to springboard, it denys me access to dial pad or contacts.
unable to make phone calls

i have 2.0, also tried 2.02 and exact same problem.
after i restore 2.0 or 2.02, i tell itunes to setup as a new iphone. i do not restore any backup files, none.

i have tried this from 3 computers, using itunes 7.7.x with winpwn 2.5 beta 2

when i restore 2.0, then use cydia to download apps, then i ssh and upload my ringtones. i use cydia to add winterboard, appbackup, then download my appstore apps

everything works in the last case it all worked for 5 days
then i wake up today to try and make a call and it wont do it
i try rebooting, resynv to itunes, nothing

this is frustrating because i think this is the 5th time this has happened to me.
i can't figure it out, each time i setup my iphone as new, never restore from backup.

i've done this so many times yet i cant figure out why it works then a few days later, it randomly decides to fail and only way i can fix it to again restore.
