Q: just bought a  iphone4s, moved the sim card out of my old iphone4 to the new phone. Everthing was fine for 2 days. Now a lot of contacts got dumped/ 2 pages in notes, and most of my appointments, past and future. I back up to the cloud about 2/3 x a week

bought an iphone4s. moved the sim card from my iphone4. did a sync on my computer, and all of my apps showed up. Calendar good, notes all there....Two days later, I lost most of my contacts, 75% of my appointments, events are gone, both past and future.. Two pages of notes are gone. Really important info. I have synced, synced again,backed up to the cloud, to my computer, shut it down, etc. Nothing has worked! Any ideas?
