What apps are avaliable for Nokia Lumia 822?

I'm wanting to get a Nokia Lumia.
What apps are avaliable like games and apps for camera.
Also how does it compare to iPhone 4?

Because Lumia uses WP8, the app-market hasn't got much to fill itself (125 000 as of October 2012 when Google Play has 850 000 as of February 2013 and App Store has 1, 100, 000 apps as of March 2013.) Also there's the necessarity about creating Xbox Live membership to get any apps. I think it's better than iPhone 4 in terms of durability, camera and the simplicity of the UI.

  • Will discontinued apps be avaliable on my iPhone after a software update? Hi, I'm looking to update my iPhone 4 with iOS 6.0 to iOS 7.1. I have a few apps installed from the apps store that are no longer avaliable to buy, such as the original Flappy Bird. I'm concerned that these apps will not be avaliable after I update. I plan on backing up my phone first, but will the backup save these apps from being gone forever? Is there a way to prevent these apps from being deleted other than backing up my phone? Or will these apps simply be no longer avaliable?
  • Which would be better to upgrade to The Iphone 4 or Nokia Lumia 822? Reason I ask this is the Apple App store has Way more apps that I can't obtain on the Windows app store such as Instagram and Pinger. But the Iphone 4's cameras are 5.0 mega-pixel (Back) VGA (Front) and its only 3G. Where as the Nokia lumia is 4G its cameras are 8.0 mega-pixel (Back) 1.2 (Front). Please advise
