George Hotz, who gained notoriety when he unlocked the original iPhone, has released a jailbreaking application for the iPhone named purplera1n. For now, it's Windows only (Windows 7 not supported). The jailbreak requires the latest version of iTunes and an iPhone 3GS with firmware 3.0.

In a presentation at a conference today, Mac security expert Charlie Miller highlighted a security issue in the iPhone OS that could allow root access to malicious code via SMS.

Facebook today confirmed that Facebook for iPhone 3.0 is coming "very soon" and it is 98% done. It appears to be a significant upgrade and push notifications are in the works for the 3.1 update later this summer.

Those who use Tweetie (App Store link) as their Twitter client of choice will be pleased to find out that an update has been released that fixes the issue that would cause one search result to display at a time. The new update 1.3.2 is available for free for registered users. Tweetie itself retails for $2.99.

Typically, we find ourselves reporting on Apple declining an application for entry into the App Store. Today we simply find humor in the fact Mariolife (App Store link) somehow received approval. According to Daring Fireball, the App Store team does not deal with copyright and trademark issues when reviewing an app for entry. Huh? Again perhaps we hoped they would deal with common sense.

With iPhone OS 3.0 available to the general public, it appears Apple is hard at work on the development on iPhone OS 3.1 which is now available for download if you are a registered developer. Find anything interesting? Let us know in the comments or in our forums.
