Sorry, I'm a litle bit of a gramma Nazi lol. It's actually more stable, not more stabler. Aside from that, how do I upgrade to just iOS 4..? And about compatibility, imo 4.1.2 would in theory have more compatible functions.. being that some apps require it to download. But, seeing that two people have both said stay on 3.1.2 it's probable that's what I'll do.
