Some very exciting developments in the iPhone apps world this week.  Check out these 3 must-have apps:

1.  DropBox

Create an account at GetDropBox.com, then effortlessly sync files between your home computer, work computer, and your iPhone.  You can even take pictures/videos from your iPhone and upload them directly to your computer. Cost: FREE.  This absolutely kills the $4.99 Air Sharing app’s revenue model.

Amazingly seamless syncing of files between your computer and iPhone.

2.  RedLaser

RedLaser uses the camera of your iPhone as a barcode scanner.  Scan anything from books, to candy and it will instantly search for the product on Amazon and Google.  Great for price matching when buying electronics.  Cost: $1.99.

Hold over any barcode (RedLaser)

Runs search on Amazon and Google for the product.

3.  ZipCar

Much anticipated ZipCar app is finally out.  Find a nearby car using the built in GPS function, reserve it via the iPhone interface.  Once you initially unlock the car with your KeyCard, you can then unlock/lock/honk the horn from your iPhone.  Really impressive stuff, and will definitely up my Zipcar usage.  Cost: FREE (Zipcar membership required)

Locates Zipcar locations near you.

You can unlock, lock, and even honk the horn using your iPhone.
