I found CalAlarm in the AppStore for $1.99 that goes way beyond what RemindMeLater does as a JB app by providing a full-fledged calendar app (which aint bad) and a snooze screen for alarms that allows you to customize 11 different snooze durations exactly to your liking... minutes, hours, or days. When an alarm goes off and appears as a notification or in notification center you just tap the item, it opens up in CalAlarm right to the Snooze screen, you tap the snooze duration and you're done!
Ridiculous that there is only ONE calendar app of the hundreds in the AppStore that does this. But, at least I now have a great snooze option. I was actually starting to think about switching to another smartphone OS because of what a productivity decriment this caused for me... only one shot at an appointment alarm and that's it with native iOS. Wow. If you have a lot on your schedule or have a lot of appointments as part of your day and can get along without snoozes, more power to you. But, a big sigh of relief for CalAlarm... well worth $1.99.
