I’m in my second month of using an iPhone. I had reservations about getting an iPhone due to cost (both of the phone and the data plan) but I have no regrets.
To get started with my iPhone I’ve added several productivity, social networking, and media apps. The first thing I really needed was a good task management app. I chose Toodledo because it was the best full featured app that works with Google calendar. I had been using Remember the Milk with Google calendar but I found that Toodledo has more features.
I also added Evernote. I’m still working on how I will use this app to corral information from many different sources. I like the interface and the fact that there are web and client versions of the software all which sync. I only wish that the software had a way to capture a drawn note such as YouNote. I’m still searching for an app that will allow my to draw on the screen.
I added the Google app but I’ve been disappointed that there is no method for entering appointments on the calendar there. I ended up synchronizing the iPhone calendar app with my Google calendar. I have also installed the Google Earth app.
For social networking I added the Facebook app and the Twitterific app. I hear the Tweetie app is also very good.
Other useful apps I’ve installed are Pandora, Urbanspoon, NYTimes, and Stanza. I’m still searching for an app to extend the camera and photo functionality. I did find the Griffin Clarifi case and I’m considering purchasing it to improve clarity, especially for recognition with Evernote.
