Yes, if you go to 3.1.3 you can revert to 3.1.2 but 3.1.3 will not help you with the problems your describing. The only thing I'd say to do was restore and re-jailbreak but I don't see why that would help. Good Luck.

It's no revelation, fixing only the accuracy of the 3GS battery meter and the stability of some third-party app launches. - "Gizmodo"

Be careful on what OS you put on the 3G. Since 4.0.1 has come out, Apple is no longer signing 3G firmware versions just like on the iPhone 4 and 3GS. This means that if you make a mistake and mess something up, you can only rsetore the phone to the current version.

That's not true. You can always restore a 3G to 3x.

From the Dev-Team:
Those of you with jailbroken iPhone3G and ipt2G devices may now have noticed Cydia starting to save your SHSH blobs too, just like it does for iPhone3GS, ipt3G and later devices. That’s because starting with 4.0, Apple started putting a “soft” SHSH blob check in the firmware. The SHSH blob check is very real in the sense that if iTunes can’t get your blobs (because the Apple signing window has closed), the iTunes restore will error out. But it’s “soft” in the sense that those devices can always use redsn0w or PwnageTool to get past the error (the bootroms themselves for those devices don’t require blobs to be in the firmware files, unlike the newer bootroms). Furthermore, since the 3.x IPSWs for these devices don’t enforce it, you can always restore to 3.x IPSWs outside of any signing windows.
So, Cydia is doing this to allow you to continue to use iTunes to restore to 4.x on iPhone3G and ipt2g outside of Apple’s signing window without needing to use redsn0w or PwnageTool to get around Apple’s annoying new restriction.

Saurik was referring to 4.x signing. You can still restore a 3G to 3.x because signing is not enforced on the 3.x ipsws for the 3G.

You are correct, I just assumed what I posted above. Sauriks tweet was very brief so I took it at what it looked like it was saying. Glad to know 3.1.3 and earlier are still safe
