Rumors have surfaced online that Apple and its partner AT&T Wireless have ceased to offer the iPhone 4 without a two-year service contract. Speculation on the issue has blamed the policy change on everything from an impending Verizon iPhone to AT&T greed. These reports would be informative except for one thing, the rumor is not true.

Both AT&T and Apple offer the iPhone 4 without a contract at no-commitment pricing. However, these deals are not available online. AT&T representatives have verified that the iPhone 4 can be purchased without a contract in person, from either an AT&T Wireless retail store or an Apple Store. To have an iPhone purchased online and shipped to your residence or place of business, a two-year contract is required.

According to Oprah Magazine, StumbleUpon is not only the most addictive website ever, it's also the "greatest thing ever invented." Well now you can have all this on your iPhone with the StumbleUpon app. The app will look familiar if you're one of StumbleUpon's almost 11 million members.

With an embedded browser, the StumbleUpon toolbar has thumbs up and thumbs down buttons along with a home button and random stumble option. In order to use the app you must have a registered account with StumbleUpon. What sets the iPhone app apart from the desktop version is a focus on mobile-web specific features and content.

Vimeo has expanded its embedded video offerings to include iOS optimized HTML5. The video sharing site first launched iPhone-compatible viewing earlier this year with a limited selection of content. Although selections have been greatly expanded with the Universal Player, there are still videos that require a Vimeo Plus account to view on a mobile device.

Vimeo is even offering a Javascript snippet to help automate the embed code updates for those who have posted content on their web sites. The Universal Player has been under development for some time, and Vimeo plans to add support for more players as needed.

Overwhelming demand for the iPhone 4 took down Korea Telecom (KT) servers during the launch of pre-ordering and resulted in 130,000 units sold in just 13 hours. The device will ship and hit shelves at 2,900 KT stores nationwide in September. Pre-ordering began at 6:00 AM local time, with the first 100k units sold by the end of lunch hour.

In contrast, the iPhone 3GS sold 60,000 units over five days in South Korea when it launched in December 2009. KT is the second largest wireless provider in the country, and although the company increased its web server capacity they did not expect demand to be so strong. Web ordering went down intermittently throughout the day, with traffic swamping the available bandwidth. AT&T and Apple had similar issues with pre-ordering in the US this June.

Apple has released a security fix for iOS 4 and users now have to decide whether or not to install the update. There are pros and cons to installing the update, mostly revolving around whether or not you're interested in jailbreaking your device. The security problem was first discovered and used by the Dev-Team to hack iOS 4 and provide a simple way to jailbreak through the Safari browser.

Now that Apple has released a fix, the developer responsible for the JailbreakMe 2.0 in-browser jailbreak software has made the source code of his exploit public. Let's be clear, the iOS 4.0.2 update will make jailbreaking with JailbreakMe 2.0 impossible, however now that the source code of the jailbreak is public, security threats are bound to multiply.
