I've had a Blackberry for close to a year now, and recently got an iPod Touch. I've been wondering, with all the available technology in my pocket, is there anything I can use to help with the development process? Perhaps something to get on a VPN? Maybe something to view SVN/CVS commits? Any source code viewers, with syntax highligh...

In a lot of iPhone apps, I see a UITableViewController being used as a checkbox list. (See, for an example of what I mean, Auto-Lock under Settings) While trying to implement this myself, I had to jump through a lot of hoops in order to have an item selected programmatically by default (ie., the current value for what the list represe...
