iPhone 3G upgrade (yes upgrade) to 3.1.2 OS

I just dug out my old 3G iPhone which I bought in 2008 & used for about 10 months before chucking it in a draw & forgetting about it due to poor performance (the iPod would crash the system). I've just got it out & started to use it again. It's operating system was never upgraded from its original one. None of the Apps work anymore and it's coming up with a dialogue box stating that I need to upgrade to the 3.1.2 OS in order for any new Apps to work however I can't find ANYWHERE (not even Apple) which still has this OS. It has never been hacked/jailbreaked, it just needs to be upgraded to 3.1.2. Does anyone know where I could find this and know how I can install it?

Thanks

To use that file, connect your iPhone by USB and in iTunes, hold down the OPTION key while pressing the RESTORE button. You can then browse for that ipsw file.

Actually, you want 3.1.3, which is downloaded by you simply by synching the iPhone to iTunes. You'll get an alert.

Thanks for that. Much appreciated. Funny, now I can't find any Apps which work on the 3.1.2 OS. They all seem to need 4! lol. The iPod doesn't crash anymore though. Bonus!

No, syncing the iPhone 3.0.1OS to iTunes only offered the install of OS 4. After everything I've read about slow performance theres no way I'm going to do that!

What does the 3.1.3 offer thats better than the 3.1.2?

Yes, that's one of the biggest aggravations about the iOS ecosystem. You have to keep up and make backups because once the developers drop support for an older OS, you can't get an older version you can use.

Wise decision.

Final tweaks, bug fixes, security patches. IIRC. At any rate, there's no reason to not go with that.
