I couldn't decide where to post this so I put it here, feel free to move it.
With the 2.0 firmware coming out to coincide with the iPhone 3G launch, lots of iPod and iPhone applications from 3rd parties appeared. A lot are free and there are a good amount you need to pay for. Pay for apps include a fair few games like MonkeyBall, Crash Bandicoot, Poker, Brain Challenge, Sudoku etc.
The only one I have paid for is Pool which is fun and was £3.50 or £3.99 something like that.
The free apps are where it becomes impressive and it's not only games.
CubeRunner was free at first and it's a bit like F-Zero but you use the accelerometer to tilt the Pod and that controls your little plane to avoid the blocks.
Aurora Feint is a free game which is a bit like Bejewelled but with an RPG style levelling up system where you unlock more skills and items as you go. That's a good one.
Advent is a text based MUD, it's an old game called Adventure-Collossal Cave which some of us older peeps might remember, where you type in look, pick up, north, open, use etc.
Morocco is a free version of the game 'Go' with the white and black counters, and there is a free Mah Jong game too, which is shit.
Remote is a cool thing which allows you to control iTunes on your PC over your wireless network, it works really well and you could prank someone with it quite easily. Also handy if you have good PC speakers and cba getting up to your PC.
Scribble is a sort of stripped down MS Paint, but you can use anything you draw as a wallpaper for your Pod which has given me endless fun.
Stanza is a free eBook app which has hundreds of eBooks you can download, mostly old classics but some of the new creative commons stuff as well.
There are a legion of news feeds like NY Times, SportsTap, SourceForge, Mobile News Network and many more.
There are streaming apps for internet radio, although none of them so far work for BBC radio because they use Windows Media guff instead of MP3. Still some good foreign stuff on there.
You can get MySpace, Twitter, several social network sites have apps, that crap doesn't interest me, although they are popular a lot of people like them.
InstaPaper lets you save web pages to read offline, useful.
There are dictionaries, apps which turn your screen white and bright to use as a sort of torch, weather, stock prices and countless web-based apps you access through Safari like hundreds of games etc and the Daddy of them all BBC iPlayer.
All for free. As long as you hack the firmware upgrade, otherwise that part costs a tenner.
I hacked mine and everything works fine, iTunes doesn't seem to notice or care.
What apps do you like to use? if applicable..... if applications are not applicable then back your way out of this semantic mess.
