Today I managed to downgrade my iPhone 3G to iOS 3.1.3.  I found out the issue that I thought was preventing me previously was only applicable to 3GS and above.  My only real problem was lack of backup as all of the active backups I had were after the iOS 4 upgrade.  But all of my data is either on my computer or cloudward, so I went ahead, did the downgrade according to lifehacker and told iTunes to treat it as a new phone rather than restore from backup.

Now I am on 3.1.3 (unbroken) and running only slightly slow rather than painfully slow!  Soon I plan to re-jailbreak though.  There doesn’t seem much point in not doing it, if v3 of the OS isn’t going to be updated any futher!

That’s all for now I’m afraid!
