how do i compile my iphone in xcode4 in to a ipa

I am a newbie here and i want to know how do i compile my iphone app in xcode 4 with a fake code sign?( pleaase include files if any.)

more info - i have made my iphone app in xcode 4 and tested it in the iphone simulator and all appears to be working great.

now i want to compile it for cydia submission, but when i look at the fake code sign idid on 开发者_Python百科the big boss website, it is the old xcode3.

so please help me because I REALLLY WANT THIS APP TO GET OUT THERE and people to use it.

thanks.

1. Create a folder called Payload
2. Place the .app folder inside of that
3. Zip up the Payload folder using normal compression
4. Then rename the file with a .ipa extension

That's it! No image will appear with loading it in iTunes.
