Restore Latest 4.2.1 Backup on 3G Running 3.1.3

[StangGT909]

Is it possible to restore a backup made today with the latest 4.2.1 software, on a 3G iphone that has been downgraded to 3.1.3 ?

Got sick and tired of the slooow speed and downgraded and it's as fast as it used to be (even faster than the latest 4.x software).

But now I can't install my backup.

I can't find any guides with a work around and fear I'm screwed.

Is there any way to make it work?

You can't install backups when downgrading, unless you still have a backup saved under 3.1.3. So if the only backup(s) you have are above 3.1.3, you gotta start from scratch.

This is one caveat of downgrading to 3.1.3

That stinks. Oh well, contacts, music, and iphotos still came back. I guess the Angry Birds saved games are the single worst thing I lost. I would have thought someone would have invented a utility by now that would assist.
