Import iOS 4 sms.db into iOS 5?

I plan to update to iOS 5 this weekend and was thinking I would do a fresh restore this time. The only thing I need other than my Exchange contacts and calendars is my SMS.

I was wondering if they made any major changes to SMS.db making an iOS 4 sms.db incompatible with iOS 5. Will I be able to just SSH my sms.db out before I restore and SSH it back in after the iOS 5 restore?

I've done this every iOS upgrade since 1.x but want to make sure that iMessage didn't make any changes.

Has anyone done this? Anyone try notes.db? callhistory.db?

iPhone 4 32GB on 4.1 with 01.59.00

No, this DOES NOT WORK.

SMS Messages do not show up from restored sms.db

I'm restoring from iTunes backup now and I hope that works...

ya i actually ended up getting it to work just like you said

the permissions dont really matter as long as owner can read and write. thats 600. anything above that will work. stock is 644 so i leave it at that.

what was my problem was that i wasnt changing the owner from root to mobile so mobile couldnt read...

thanks for clearing it up here
