iPhone apps

[interested]

OK - so amongst all the crap (Monkey Ball, Facebook etc) which apps have you downloaded and found to be particularly useful/good?

My list:

AroundMe
Shazam
AirSharing
Texas HoldEm
BA Flights
Traffic UK
London Tube
Bloomberg

Just downloaded LondonCam but don't know how useful it is yet. Allows you to see TFL traffic cameras around London with a 15 min delay. Seems to be quite cool.

[Moscow Mule]

In sort of most used order. I've only got an iPod touch though, so I'm limited to wifi access.

Apps:
Things
Remote
London City (Tube)
Light
Digital Clock
AirSharing

Games:
B-gammon
HoldEm (the apple one)
Wurdle
