iphone - publish app to app store using application loader -

I have an older version of iPad SDK OS 3.1.3 and I have created an app using that app. I prepared the app and ready to upload to the App Store In the app store, I created a new app and provided all the required details. Now it is showing "Waiting to Upload" since Apple's "Application Loader" is not installed because of the iPhone SDK OS 3.2 and above, in my Mac. Therefore, I used to help my friends use their Mac and that is the latest iOS SDK 4.1 and it has also been installed "Epiton Loader". Now I copied the app's zip file to my friend's Mac, logged into the iTunes Connect account, started the application loader. It says that "no eligible application was found" How should I now upload my app?

I can not make my app using the latest SDK, because I am using the Twitter and Facebook libraries which are based on iOS 3.1.3, if I want to download them optimized for iOS 4.1. I have to do all the tests again, which can mess up my code.

Can someone please suggest uploading my app?

Some neuter questions are going to ask, but they are always worth asking:

Have you created a new version of your application in Connect? This error usually means that the app loader can not find any application in any iiune connectivity which is expecting a binary upload.

Are you sure the application maker is not using its developer account?

You are also going to hate this advice, but take a plunge and upgrade to 4.1. Yes you have to check your applications again, but it is a good thing to think in my opinion 4.1 (which shows a large part of all the future devices and installed devices) and it ensures that it Works for the old operating system, but it is to fix the obsolete OS and it hopes that it works for the latest and greatest
