no i'm having the same problem as f.stop too. before upgrade, battery last 3-4 days. after upgrade, 2 days MAX. so i restore the phone, set push notification to manual, set APN value to other stuff, all GPRS and EDGE turned off, still draining 50% per day.

maybe i'll try Shock advice - to set up as new phone after restore. but that'll be next weekend.

one question tho...set up as new phone meaning i have to SSH the contacts into iphone manually?
