I love my iPhone, ever since I took the plunge (having waited until the launch of the 3G) I finally feel that I have a mobile device which lets me use online systems without jumping through hoops, by which I refer to tiny screens and that godawful, annoying keypad text entry. The list today is of some of my favourite iPhone applications - including both installable apps and web apps.

1. Twinkle - A simple Twitter client, but as far as I know, this was the first client to use the iPhone's location service to update your Twitter location and display Tweets from near your current location.


2. Hahlo - An online app which still ranks amongst the best clients for Twitter on the iPhone.


3. Twitterific - The third Twitter client in my list is a Swiss-army-knife for Tweets.


4. Last.fm - this application is a mobile version of the Last.fm music player, it relies on a Wifi connection so only useful at home or in the office for me.


5. Flickup - A Flickr client for the iPhone which enables full resolution uploads and automatic Geotagging in addition to adding a title, description and tags to the pictures.


6. BBC iPlayer - since iPlayer became iPhone compatible, I now regularly use it to watch TV in bed. Like Last.fm, it requires a Wifi connection to work.


7. Eventful - This application makes it easy to find out events that are taking place near to you current location.


8. iTalk Recorder - A high quality sound recorder which allows you to append a new recording onto an existing one.


9. Shazam - The service which listens to a clip of music and then tells you what it is. No more wondering what the music on that TV program or advertisement is.


10. Google Mobile App - an optimised way to access not only Google's search services, but also, GMail, Google Reader, Google Docs and many others.


11. TimeTracker - A simple little application which tracks the time that you spend on any task. Cleverly doesn't need to be running all of the time to track time elapsed on a task.


12. Brightkite - Brightkite is a location-aware social network which was something of a pain to use until the iPhone app was released so that you no longer need to search for your location to tell Brightkite where you are.


13. Facebook - This app has pretty much killed my use of Facebook in a web browser. Unfortunately it doesn't let you use any of those fantastic Facebook apps. (Did you spot the sarcasm in that last sentence?)


14. LinkedIn - Facebook for professionals, another app that has nullified my need to visit the site with a web browser.


15. Galcon - This RTS game is amazing, especially when played with workmates over the local network. The great thing is, if you're not doing well, it doesn't matter - the games rarely last more than a couple of minutes.


16. Fieldrunners - A simple implementation of the desktop favourite Tower Defense, this game can soak up hours and it's terribly addictive.


17. MazeFinger - Fast paced, load and fun, Play this just for the joy of hearing a robotic voice chanting "Awesome" at you.


18. Thereminator - It's amazing how much fun you can have making weird noises with this, or in my case trying (unsuccessfully) to play the Doctor Who theme music.
