Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I'm not sure about storyboards, but with general purpose views it is possible to use the same for both iphone and ipad. You have to edit your app delegate's didFinishLaunchingWithOptions method to point both userInterfaceIdioms to the same nib.
The main challenge, though, would be to actually design a UI that still looks ok in all sizes. Struts/springs give you a little control here, but you can't do anything advanced. Constraints are a little better, but not much. If you have to resort to custom code for UI element placement, you are probably better off making separate nibs or storyboards for each device anyway.
Are you getting an error that says "too many redirects"? I'm not sure how many you're using but generally that only happens on excessive chains or an infinite redirect loop. Your options may be to either change your web server to use fewer redirects, or actually process them in stages by coding it manually (not recommended).
Also, make sure you are testing on an actual device, the simulator can handle networking differently.
