iPhone 3G, 3.1.3 w/ BaseBand 06.15.00??

[kmmxracer]

I just got a traded out refurbished iPhone 3G from Apple the other day and it came with iOS 4.1 with bb 5.14 or what ever it was. So I had to do the iPad base band upgrade to get it unlocked.

I was wondering if anyone has attempted to go back to 3.1.3 with this new iPad base band yet??

I want to get back to 3.1.3 for speed and reliability reasons, but am reluctant to try it in fear of something going wrong!!

Any ideas?

Nothing will go wrong, it should work, go for it : Speed and Performance and still be able to unlock. Best of both worlds.

I hope you are right I'm tired of my wifes 2G running better then my 3G LOL.

Guess I'll just make a costume 3.1.3 ispw and give er a go. Thanks

Worked like a charm

-Used Pwnage Tool 3.1.5 to make a custom 3.1.3 ipsw and restored to it.

It didn't even error out or anything. Thanks again!!

so you're on FW 3.1.3 with baseband 06.15.00? Does the GPS work properly?

Just for anybody interested, 4.x does offer a few new features that you may like. For instance camera zoom, folders, etc. You can maintain performance and keep those features by staying on 4.x (except wallpaper and multitasking, that's what really drags older devices) by disabling multitasking and wallpaper either through jb tools that allow those options or Cydia tweaks (such as myOS). my iPT 2G was horrible on 4.1, but after disabling those two features, it ran like it was on 3.1.3 except I got to keep my folders I like those folders lol.

Hi,

I am in the exact same situation as kmmxracer.

Expect I am a Windows user, I can't seem to find anything online on how to downgrade back to iOS 3.1.3 without using iTunes which I figure is a bad idea since I am on baseband 06.15.00.

Any help would be greatly appreciated
