1. iphone icon, ipad icon size
2. plist file’s icon file is blank (seems like can’t have file called icon.png otherwise both iPad and iPhone will use that)
3. Does not see archive in organizer after building archive:
For the “Release” configuration do the following:

Set “Skip Install” to YES on your project

Set “Skip Install” to NO on your application target

Set “Skip Install” to YES on all static library targets that are included

Choose Product -> Archive from the menu.

4. plist file, set bundle id to be same as that in iTunes connect
5. don’t need to mess with entitlement file (any more as of Xcode 4 i think)
6. product menu -> edit scheme -> archive, use right build configuration
