iPhone app recommendations

Tonight I was asked by a friend (who just bought an iPhone) to provide a list of recommended iPhone apps from my collection. After typing it up, I thought it would be nice to share this with everyone :)

The following apps are free unless specified.

Essential

• Google
• Facebook
• Fring (IM client that also allows you to make VOIP calls)
• Skype
• Tweetdeck and/or Tweetie 2 (Paid app. I'm only using version 1 right now, but version 2 should be much better)
  
• Discover lite (turns your phone into a wireless drive and allows reading DOC, XLS, PDF documents)
• YouVersion Bible app
• Logos Bible app
• Flickr
• UStream (turns your phone into live webcam)
• Dictionary.com (offline dictionary)

My photography apps

• ToyCamera (Paid app. Gives you some good lomography effects. But doesn't allow you to apply filters to existing photos in your library...which sucks)
• Tiltshift Generator (Paid app. Makes pics look like miniatures...and gives a fake SLR effect).
• CameraBag (Paid app. One of the most highly rated photo apps on iTunes, yet a bit overrated in my opinion :P. Allows you to apply filters to existing photos).
• Photoshop.com mobile (Basic photo cropping/manipulation).
• Panolab lite (Stitch photos together)
• Free Photo Filters (4 basic filters... 2 of which I use a lot)
  

Other cool apps

• Tap Tap Revenge 3 :)
• Touch Hockey
• Flight Control (Paid app. Classic iPhone game)
  
• Kotoba! (Japanese dictionary)
  
• PayPal
• CommBank (if you are a customer)
  
• Flashlight
• Pocket Cinema (cinema sessions times and ticket ordering)
• TyroTuner (guitar tuner)
• Guitar Web app (guitar chord finder)
  
• Pocket weather lite
• RDP lite (to access your desktop via the RDP protocol)
• Mars Hill Church
• Domino's pizza
• Whitepages
• Shoutcast and/or Y! Music (online music streaming)
  
• Google Earth
• Motion X GPS (Paid app. But there's also a lite version with ads. An alternative to Google Maps).

Are there other apps that you would recommend?
