Your MUST HAVE apps on the iso5/iphone 4s?

What are your must have apps for the iphone/ios? be it games or something you use daily? I ask this becasue I am getting a iphone 4s, been on the 3g for a while and wondering what apps people are using, I use the NYTS app daily, it tells you delays on trains and updates on the spot.

The ones I use quite often are:

• GoodReader (document reader that syncs w/ dropbox)
• Reeder (news reader)
• WolframAlpha (when I'm too lazy to make my own calculations)
• ProCamera (I think it's tons better than the default camera)

DropBox

Flashlight

Coin Flip (comes in handy, believe me)

RedLaser

Scanner Pro

iTeleport (best remote desktop controller in the appstore)

AppShopper (great for finding sales, can even have it notify you when an app you have in your wishlist goes on sale)

Netflix

Pandora
