I beg to differ on this whole "call recon right away" thing. True that recon has the ability to approve your app, but they also have the ability to deny your app. If you just let the system do it's thing, alot of times you will get the approval email a couple days/weeks later (especially with Chase business cards, you won't have to deal with answering recon's million questions).
Whenever I'm done applying for cards, I'll always just throw another one in and not call about it to see what happens, and my experiences so far have been pretty good!
Feel free to share your opinion.
