After seeing that SBSchedule was reported as working with iOS 4 I downloaded it to my iphone 4. I've had nothing but problems. When trying to setup schedules, it keeps crashing as I add events to the "ON" or "OFF" category. While it allowed me to name the first Schedule, all other schedules are simply listed by the trigger time noted in the schedule itself. But most troubling, is that it keeps crashing when I'm trying to create a schedule. I have now turned off the one schedule I was able to create -- I'll just wait for the next update.
