Well Enigmo is on sale for 2 or 3 bucks and Monkey Ball just works great with the iPhone. Also, just today I bought line rider for $3 and I love it. Neat apps that aren’t games include koi pond, iLightr, siesmometer, X-Plane and weightbot. Hope that helps.
I’ll 3rd the Enigmo recommendation – best game in the app store IMO. Lux is also very good (and free!). Dashball & FS5 Hockey are also good. Non-games: RJDJ (unbelievably cool), runkeeper, BrightKite, twinkle.
I liked the look of enigmo, bought it and enjoyed it, but found it very difficult to play. I like simpler games: wurdle, line rider, bejeweled and space monkey.
shazam is a program that listens to the music you expose it to( radio, parties) and identifies it, tells you what album you can find it on. Even
links to iTunes. Totally awesome!
STEP ONE: download the free Pandora Box app.
STEP TWO: look for either new or on-sale apps that are free.
STEP THREE: add each one that you like to your favorites.
STEP FOUR: consider 5 or so to get at a time and download them from the app store.
STEP FIVE (OPT): if you actually have money, look for on-sale apps for 99c or so.
STEP SIX: if you follow step five, repeat steps 3–4.
STEP SEVEN: enjoy!
