HELP: IPHONE APP REQUIERES IOS 4.2 OR LATER

[kokoito]

HI ... I developed an iPhone App and it works great on my iPhone2G with 3.1.2 firmware when i built it with mi Develop Certificate and also works great with my iPhone 4 with 4.2.1 firmware... but i have a problem!!! I uploaded my app into the App store... and when i try to download it on my iPhone with 3.1.2, App Store said me that my iPhone needs firmware 4.2.1 or later to download...

Somebody knows what i need to do to resolve this problem?
I need to change some configuration o my target info?

I used these frameworks:
*AudioToolbox
*AVFoundation
*CoreGraphics
*Foundation
*MediaPlayer
*MessageUI
*Quartzcore
*UIKit

You didn't set the Target sdk in settings.

I just did the same thing, here's what happened: You created a new target for doing the build to go to the app store. The target OS didn't propagate when you made the new target. Update it and submit a build to the AppStore, I've gotta do the same dang thing. Lesson learned, le sigh.

So I basically i need to do these steps?
1.- clean al targets...
2.- select the target and get the info...
3.- at the go to the tab BUILD and change the checklist configurations to Distribution...
4.- Go to the Deployment section and change it for 3.1.2? and then BUILD...
5.- convert to .rar and upload?

Thanks

Yep. I got to that screen by selecting 'Edit Active Target (project name)', but the rest sounds the same.
