BUG: Missed a text message yesterday, came back to phone and IS was up (phone did not sleep) and battery was almost dead. Had this issue with missed calls a few versions ago, and it's a deal-breaker for using any alerts
iPhone 3G, FW 2.1
IS settings for IntelliAlerts: AlertView ON, Taskbar Icons ON, Swipe Alert OFF, Missed SMS ON, Missed Calls ON, Mail and repeat CAL OFF, SMS Privacy ON.
Let me know if you need any more info! Thanks!
