This app -- which uses the iPhone's camera to scan barcodes in order to bring up a description of the products as well as what it's selling for at various online sources -- is truly a breakthrough development for the iPhone.
This collection of 21 utilities isn't slick, but that doesn't detract from its usefulness. Bundling nearly two dozen apps into one package means you'll get good value out of AppBox Pro, even if you wind up using just a few of its utilities.
This app makes it easy to send short messages from your iPhone or iPod touch by storing canned text for later use in e-mails or SMS messages.
