Here I give you the Top 10 FREE  iPhone 3G apps for your iPhone:

Remote

Be a mobile DJ. With Remote, you can control iTunes on your computer or on Apple TV from your iPod touch or iPhone. Play, pause, skip, shuffle. See your songs, playlists, and album art. Update to iTunes 8 and you can create a Genius playlist or edit an existing playlist. And do it all on your iPod touch or iPhone as if you were right in front of your computer. Remote works with your Wi-Fi network, so you can control playback from anywhere in and around your home.

Box Office

With Box Office, if you want to see a movie and don’t know what’s playing, you just open it up. It’ll detect where you are, find theatres around you, and list movies playing by their RottenTomatoes score. Want to get tickets? Click on the time you want and it’ll toss you to Fandango to buy them. You’ll get the whole process done in no time. If they added streaming trailers in to this app somehow, it’d really be taken to the next level, but even as is it’s one of our favorite apps so far that we’ll definitely be using all the time.
