There was a member who posted that the pre's alarms/tasks/calendar were a problem for him because he wasn't getting notification to take his meds. While skimming through the iphone web apps, I came across one that may work for him.

It's free to sign up. I didnt test it out, but perhaps it will be a help. I tried to find his post so I could just send a PM, but I searched and couldn't find it. Maybe someone will remember who it was and bring this to his attention.
