The Edge Browser, a new application that Apple has approved. Credit: Technology Review

Apple has finally begun approving third-party Web-browsing applications for the iPhone. Some of these third-party app submissions date back to October of last year. As MacRumors points out, Opera was previously refused by Apple because it was thought to "duplicate" functionality that the iPhone already offered. So it seems that Apple's attitude has thawed a bit, but apparently, iPhone browsers must still use the WebKit engine that powers Safari. That still leaves Opera and Firefox out in the cold--for now!

Here are four new applications picked out by MacRumors.

- Edge Browser: a free Web browser.

- Incognito: a $1.00 tool for anonymizing your browsing.

- Shaking Web: a visual stabilizer for the iPhone's screen costing $1.99.

- WebMate: Tabbed Browser: an app that costs $0.99 that queues up your intended Web links for later visiting.
