My iPhone 3G home screen
This is the homescreen on my (jailbroken) iPhone. No, the background isn't from OS 4, it's part of a springboard theme.
* A little extension known as Weather Icon shows the temperature in the Weather App icon and in my status bar. (jailbroken app)
* The discs on Phone and Mail are part of the Backgrounder app that lets me run an app or two in the background (mostly used for Tweetie and Colloquy/IRC). (jailbroken app)
* Things is a task management app that is GTD-based. I've got three things due today.
* Meebo is a great little multi-protocol IM client with push notifications. It's free, but basic (and fast).
* Evernote stores my notes and such in the cloud.
* Tweetie is my Twitter client of choice.
* Byline is my Google Reader client right now. I've tried Reeder but it's just too slow on my 3G.
