iPhone apps

My list of suggested applications (subject to change):

• Usual recommendations: Facebook, Skype, Yelp, Dropbox (see http://geekxperts.blogspot.com/2009/11/online-storage-and-backup.html).
  
• For IM: Nimbuzz. It is free and lets you join multiple accounts at once. It has a "stay online" period of up to 30 minutes after you close the app that pushes new message alerts.
  
• For text messaging: TextPlus. This one is free, and lets you send text messages as a group. Great way to reach multiple friends at once. It has push.
• For music: Pandora, Last.fm, and maybe imeem.
• For movies: Flixster. You can link it to your Facebook and Netflix accounts.

Now some extra interesting stuff:

• For reading books: Wattpad, Stanza. Both offer lots of free books, and a good reading experience.
• Cheap games: Tap Tap Revenge 3. You can try Tap Tap Revenge 2 before buying this one. But if you like version 2, you won't be disappointed to buy version 3 for just $0.99.
• For remote controlling your computer: AirMouse. This one I really love. Especially when watching a movie or listening to music, you can easily pause, rewind, etc. Also offers a nice touchpad mouse, and some programmable buttons.
