Is it possible to downgrade to 3.0?

Like so many other people, I am suffering from 3.1 software. The phone is extremely unresponsive, so much that it becomes unusable as a phone! Calls time out before I even manage to answer them.

Is it possible to downgrade to 3.0 preserving my data? I tried, and managed to get 3.0 installed again, but then iTunes wouldn't let me restore my backup, saying it is from a newer version of the software. Obviously a phone without my data isn't of much use.

I am stuck and becoming desperate -- 3.1 software made my phone unusable.

Mac Pro, Mac OS X (10.5.8)

Hi,
If by disaster you mean it behaves like molasses you might try a restore as new.
If you have data in any of the apps you will need to back this up and not just syncing to iTunes. The restore as new does not use a back to get things back on. You will erase the phone then start from scratch putting your apps back on. This lets the system get on the phone first. It seem to make a difference. Mine has been quite stable sine i did this and was very sluggish before.
You will have to reenter any wifi passwords and likely your voice mail pin. You can get that from ATT.
Sync any photos to iphoto too. Be prepared for a fairly long session. I have heard it is worth deleting the download of the 3.1 upgrade and then downloading it again. I did not do this and mine is fine. The procedure for that is on here somewhere.
The problem we are having is due to the memory management of the phone apps or the system. The memory gets low and apps crash. There is a great App for clearing memory. Save rebooting the phone a lot. Memory Info is the name of it. I haven't had to use it much though since I did the restore.

Hope this helps...
