Appstore Uploading issue

I have set the base SDK to iPhone Device 4.0 and the deployment target to iphone OS 3.0 in the "Targets info" section as well as the "Projects info" section found under the "Groups and files" section.All the certificates and mobileprovision files matches exactly.When i try to upload in iTunes using "Application loader".It's showing me the following error.

"This bundle is invalid.Apple is not currently accepting applications built with this version of the sdk"

Please somebody help me to overcome from this issue.i have been spending days for this issue

Thanks a lot in advance

Are you sure that you have set both in the "Release" configuration? The Target Info panel is usually set to the settings for the "Debug" configuration.

Uploading binaries with your settings should definitely work, I uploaded a binary with exactly these settings (base SDK iPhone Device 4.0, deployment target iPhone OS 3.0) just a few days ago.

I think Apple stopped approving any new applications below 4.0, so you have to set your deployment target to 4.0.

Edit: nvm I read it wrong. From Apple:

"Make sure that your applications are compatible with iOS 4. All new applications and updates to existing applications must be built with iPhone SDK 4. In addition, the App Store will no longer support applications that target iOS 2.x.
