This isn't new news, but I see enough apps not taking advantage of this, so I figure it's worth repeating:
After your app is approved by Apple, immediately go into iTunesConnect and change the date of your app to be the date of the approval email from Apple.
If you do not do this, you are missing out on a lot of potential sales. Currently, if you do not do this, Apple will list your app in the "recently released" apps lists with the date of when you submitted the app. Given the average 5 business day approval time for Apple, this means your app will most likely appear buried several pages back on the lists.
If you change the date to the date of Apple's approval email, your app will instead be listed with that date. NOTE: you must use the date of Apple's email. Using another date will not work for positioning in the recently released listings.
