restore deleted icloud calendar

I was on my laptop and accidentally deleted my main icloud calendar (which synchs across my iphone and ipad)

I took my calendar on my laptop off-line, and then I grabbed my iphone and restored it from the latest icloud backup (which was 10pm last night - so I'd only lose any calendar changes I made in the last day).

The restore worked, but my main icloud calendar (and all of the data) are still missing?!

Help! I can't make it to the Genius bar for 2 days and I need my calendar now! I am lost without it.

I don't care what device the calendar gets put back on - I just need it on at least one!

Suggestions?

Thanks!
