App Store: submitting app with future release date then changing it to earlier date after it is approved [closed]

Question

Lets say I submit my app for approval now. I set Availability Date to something like Nov. 30, 2011, because I have not yet decided when I really want to release my app. Then fortunately, my app gets approved.

1. Will I be able to edit the Availability Date after my app is approved?
2. Assuming question 1 gets a yes, let's say I then edit the Availability Date to Dec. 3, 2010. Will my app be available on the App Store on Dec. 3, 2010? I've heard that setting it to a future date after it was already available will take it out of the store, I want to know if the reverse also works.
3. Will there be any drawbacks for doing this? (This is actually my main concern)

For the record, I did search for similar questions, but still not satisfied with the replies in the other posts. Thanks in advance!

Answer 1

1. Yes, you can change availability anytime.
   
   
2. (and 3.) If you start selling your app by "accident" on a date that is today or before and then revoke it and then start selling it again at later date you can have some problems. The problem will be with all the sites that scans for new apps and then present them on the promo-sites. A lot of people will look at the promos and them when searching for the app it will be gone from App Store (since you temporarily revoked it). At the later date when you WANT to release the app the promo-sites will see it as an old app and not promote it, and you will get fewer customers.
