Long time no hear from me but had to join in this discussion....
1. Palringo...I prob use this app more than any other on a daily basis. It's an IM client but doesn't support Skype. I use it at work to chat with friends that are online when I should be working.
2. Twitterific...Twitter obviously. One of main reasons I got an iPhone was to use Twitter after it was blocked my net nazis at work. Don't use it a lot anymore.
3. Brain Tuner.. Just a lil app that throws you some simple maths questions and have to do them as fast as possible. Just a quick thing but not bad, maybe a good one for the kids Dave.
4. IGN...basically game reviews from IGN network.
5 Light...Again self explanatory and some people may think it's a waste but has helped me a lot when we have had blackouts, much easier to negotiate stairs in the dark.
6. Morocco... An othello style game which basically i suck at.
7. Lightsaber...I hope I don't need to explain this.
8. Remote...If you have a mac, apple TV or really anything you should have this.
9. Tris... tetris style game, haven't played it much
10. Twinkle..another twitter client that I don't use much but has more geo-location features
11. 1Password..I have a 1Password account so why not.
12. Tap Tap Revenge...GH/RB kind of game...yea I also suck at it.
13. Cubes Lite...another game with matching squares to destroy a cube. More squares you get more points you get. Not abad game for filling in time.
14. eReader..read ebooks..which i don't.
15. Netnewswire...Dosen't everyone have this. if you use it as your feed reader on your machine you shuld have this. I read a lot of feeds on the train home.
16. Pocketpedia...iPhone app for all my desktop based pedia apps. Sync all your CD's, books and music to it.
17. Melodis Dialer...Voice dialler that actually understans Aussie accent. Works pretty good.
18. Air Sharing...Enables you to move files between your mac and iPhone..portable storage basically. haven't used it much tho.
19. Coin Toss...Don't have a coin handy. Just slide finger up screen fast and wait to see if it's heads or tails.
20. Pro Football...Updates scores and also live updating of games...NFL of course.
21. Worldwiki.. Nice little app that has lots of world facts about diff countries. very handy when you just can't remember what the capital of some country is.
22. AU Postcodes..Lists all the Aussie postcodes. can come in handy.
23. Metro Syd..Train Timetables for Cityrail.
24. pkt Weather...Great weather app and has radars. I think
25. Cricket...Great app if your a cricket follower. Pulls feeds from Cricinfo and does the live ball by ball updates. Another app I use a lot when on train home to follow game until stumps.
26. Urbanspoon..haven't used it much but it does have support for Sydney at least.
These next few I only added tonight so haven't tested fully yet...
27. Facebook..I logged on to facebook today using safari on my phone, maybe this will be easier.
28. Fring..haven't tested yet.
29 Google Earth.. If you don't know what this does...where have you been.
30. iHandy Level...why not..just for the record my table is 0.8 degrees from being flat.
31. Last.fm...had a quick trial of this and worked great with wi-fi. haven't tested under 3g, will try that tomorrow at work. Yes I created a US account but not just for this.
32. Shazam..music recognition software, haven't really tested it yet but it's supposed to work well.
33. Trism...Everyone one raves about this game. had a quck game and is stangely compelling.
34. WiFinder...maybe I can find some open wifi points near work.
35. Aurora Feint...almost forgot this one. Interesting RPG tetris game.
Obviously I don't have all of this installed on my iPod Touch as it doesn't have net connection but I have all on iPhone. That's all for now and I am pretty sure they are all free apps. Always willing to add more apps :)
