I use my Iphone calender to store all my appointments and customer information etc rather than my Outlook calender on my laptop most of the time. To the best of my knowledge I have never lost any info before, but after syncing the two devices today my calender is now empty on both. I had thought that syncing would mean taking the information on both devices, amalgamating it and populating both devices with the same info?

Two questions:

a) Is there anyway of retrieving the lost information? (or am I sunk?)

b) Is there any way of averting such disaster in the future?

Whilst I suspect that "Read the manual - Idiot!" would be the correct response, any help really is greatly appreciated!
