Hot on the heels of AT&T changing its tiered data plans once again, reports have surfaced regarding data throttling on unlimited plans. Although the unlimited option has been discontinued, some iPhone users are grandfathered into the plans and continue to enjoy no monthly limits on usage.

Only catch is that AT&T will start throttling data speeds when a threshold is reached, typically when a customer enters the top five percent of data usage. According to MacRumors this threshold has decreased significantly and now includes subscribers who have reached just 2GB of usage. This number is even lower than the 3GB tiered data plan costing $30 per month that was recently announced.

Apple plans to use Liquipel technology on the next generation iPhone, making the iPhone 5 immune to problems resulting from exposure to water. The waterproof iPhone 5 would be treated internally with a thin layer of Liquipel's material that prevents water molecules from ever contacting sensitive electronic components.

The news that Apple plans to utilize this technology comes from a source in the UK phone retail industry, who stated that wording for insurance documents will be changed to accomodate the waterproofed iPhone 5. Liquipel's technology was demoed at this year's Consumer Electronics Show (CES) in Las Vegas.

Another report has surfaced pointing to a summer iPhone 5 announcement from Apple. The analysis from Daiwa Securities claims the next generation device will be revealed at the Apple Worldwide Developer's Conference (WWDC) in June. This would bring Apple back to its tradition of mid-year iPhone releases.

The shift back to a summer release would mark a departure from last year's October iPhone 4S launch, leaving just eight months between the two generations of smartphones. The normal venue for WWDC already has the dates June 11-15 blocked off for a "Corporate Meeting" and is expected to host the Apple event during this week.

If you're lucky enough to be attending Super Bowl XLVI you'll probably want to grab the NFL's SB XLVI Guide. The free app contains detailed information about local restaurants, nightlife and official Super Bowl events. You can also use the 3D map of Lucas Oil Stadium to find your seat and locate parking. If you're not Indianapolis bound you can still download the Super Bowl XLVI Official NFL Game Program. It's essentially the same program you would receive if you attended the actual game, but with extra digital content. It features over 400MB of exclusive NFL video and chronicles the Giants’ and Patriots’ road to the championship. The app is free for the iPad only and requires a lot of space to download.

NFL Pro Tweets by the NFL Players Association allows you to follow what the pro players are tweeting about the game. You can also follow all the other Super Bowl social media buzz with the SB XLVI app I mentioned above.

Super Bowl Winners allows you to brush up on your past Super Bowl knowledge. The free version gives you a detailed history of every Super Bowl ever played with the ability to upgrade to the full Professional Sports History version. The $1.99 version offers a complete history of every MLB, NBA and NHL championship ever played.

Reports of iMessages being received on the wrong iPhone have resurfaced, this time with Gizmodo posting a slew of information not intended for their eyes. Apparently an Apple employee briefly inserted his personal SIM card into a customer's iPhone, and ever since his iMessages are being delivered to her device.

This is after the customer's iPhone was reset and her personal infomation including her AppleID was reentered on the handset. Similar reports of the problem have cropped up intermittently in the past, with Ars Technica weighing in on the issue. Support forum threads regarding the problem have sprung up at Apple and elsewhere as well.

The Corona 5.0.1 Untether package has received another update, this time to correct an iBooks problem where images failed to display or displayed incorrectly after installation. Chronic Dev Team released Corona 5.0.1 Untether to free tethered jailbroken devices including the iPhone 4 from the need to reboot with a computer.

After installing early releases of both Corona and the redsn0w jailbreak for iPhone 4 and 3GS devices, some users had problems with iBooks including a Configuration Error dialog. The latest version of Corona (1.0-7) should fix both iBooks errors and can be installed directly from Cydia on a jailbroken device.

Siri has been receiving lots of attention lately from iPhone 4S owners looking to expand her capabilities. There are more tweaks and customizations arriving every day from developers in the jailbreak community. Of course, there are still things you can teach Siri to do without jailbreaking your iPhone 4S.

Although Apple has not included support for Siri to update social networking sites such as Facebook and Twitter, you can easily set up your iPhone 4S to make this possible. Siri will then take your commands and upload the message directly to your account. The same trick can even be used to let Siri update Google+ as well.

If you've used pod2g's exploit to jailbreak your iPhone 4S you can now take advantage of the many Siri tweaks available through Cydia. There is CustomSiriBackground, which allows you to wallpaper Siri with any photo from your Camera Roll, and Sireet, which gives Siri the ability to send tweets. But the best Siri tweak of all has to be AssistantExtensions.

AssistantExtensions turns Siri into the voice assistant we've all been waiting for. It allows Siri to search YouTube videos and launch apps, but best of all it can make her hold intimate conversations with you. Saying the phrase "Lets Chat" activates the Siri chat mode. After a short wait for her to load some textual data, Siri will tell jokes and give you information without having to connect to the web. For example, asking her "what is Apple" will result in her giving you three definitions, the third being "Empire for Steve Jobs." AssistantExtensions opens a whole new world of possibilities for Siri, and it even allows you to have custom conversations if you take the time to create them.

It only took a few months but Sprint finally released an iPhone app for their customers. Like other carrier apps, the "Sprint Zone" allows users to access their account, search for promotions, read Sprint news and locate Sprint stores. There is also an Apple store locator, easy access to Apple Care, and the ability to check simple device info like battery stats and data connection. The App is free in the iTunes App Store for devices running iOS 5 or later.

Now that the iPhone 4S has been jailbroken developers are scrambling to provide new tweaks and improvements to enhance iOS 5. The Siri personal assistant is exclusive to the iPhone 4S and is already getting some great enhancements to add functionality. One example of a feature left out by Apple is the ability to update Twitter with Siri.

Apple still considers Siri technology in a beta phase, which is probably one reason why sending tweets is not officially supported. Not only this, but iOS 5 is the first time Apple has integrated Twitter into the operating system. Now thanks to Sireet, jailbroken iPhone 4S users can natively send tweets using Siri.
