Nokia Lumia 820 or iPhone 4 (8GB)?

I've always wanted a phone with a large screen (anything over 3.2 inches), front-facing camera, a decent storage space (8gb or above) and an app store with a nice range of apps.

The iPhone at my local phone store is in the $400's, whilst the Nokia Lumia 820 $389 (including a wireless charging shell and plate).

The Nokia Lumia 820 has a better camera, but iPhone4 has more and better apps. In the other hand, Lumai 820 is a bit big so that you may not hold it comforatably
