Unlike Nintendo, SEGA has fully embraced mobile gaming by bringing its classics like Sonic the Hedgehog to Apple and Android devices. There are currently 8 Sonic games available in the Apple App Store, and starting today they are only $0.99. This is a pretty good deal since some titles like Sonic CD were originally $6. Check out a complete list of $0.99 Sonic the Hedgehog games below, and prepare yourself for some awesome retro gaming on your iPhone or iPad. It's unknown how long this sale will last, so make sure you download your favorite Sonic title today!

The original Sonic the Hedgehog game that started it all is only $1! The iOS version is optimized for the iPhone 5, and features new characters Tails and Knuckles.

Sonic the Hedgehog 2 was remastered for iOS devices in 2010. However, it has not been updated for later devices such as the iPhone 5.

Both Sonic The Hedgehog 4: Episode I and II have been discounted from $4.99 to $0.99. Now you can download both episodes for less than the original asking price of one.

Virgin Mobile has announced it will begin offering the iPhone 5 with unlimited 3G/4G LTE data on Friday, June 28. Contract-hesitant consumers can nab the 16GB model at a Virgin Mobile retail store, or online for $550. The 32GB and 64GB units will only be available through VirginMobileUSA.com for $650 and $750, respectively. The Apple handset is being coupled with Virgin Mobile's Beyond Talk plan, which includes unlimited data and messaging starting at $35 a month. Virgin Mobile is also offering a $5 per-month discount plan for customers who sign up for automatic payments.

If you can't afford to drop over $500 for an iPhone all at once, T-Mobile offers the 16GB iPhone 5 for $149 down with 24 monthly payments of $20. There is no contract, but you do have to make all 24 payments even if you decide to leave T-Mobile. You also have to pay at least $20 a month for a data plan to be able to use T-Mobile's network.

2K Games's popular turn-based strategy game XCOM: Enemy Unknown is now available for the iPod touch, iPhone and iPad. The remake of 1994 PC game UFO: Enemy Unknown is one of the most expensive iOS games at $20. Early reviews of the iOS port have been positive, even though there has been some backlash from fans over its price tag.

The developers warn that XCOM is a "graphically rich game with advanced features that is best experienced on the iPad 4 and up". The game is a hefty 1.86GB, so make sure you have plenty of space on your device before you download it. It's also only compatible with newer iOS devices such as the the iPhone 4 and up, and fifth-generation iPod touch.

Apple has taught Siri how to contact the National Suicide Prevention Lifeline for depressed iPhone owners. Previously Siri would only suggest nearby suicide prevention centers when a user told her that they felt like killing themselves, but now she will suggest calling the national prevention hotline, and offer to do the dialing for them. Siri will only read the 1-800 number to suicidal iPad and iPod touch owners, who can't place calls with their devices. Apple added the new Siri service via a server-side update on Tuesday.

Siri is going to be getting a lot of new features when iOS 7 is released later this year, but Apple must have thought this was too important to wait. However, Siri still won't dial 9-1-1 when asked to call for emergency services. That you still have to do on your own.

Game developer Crytek unveiled one of the first iOS games to feature MFi controller support at the Worldwide Developers Conference last week. 9to5Mac reported that Crytek demoed the controls of a tactical action game called The Collectibles while using the form-fitting Logitech controller prototype created for the iPhone. This is one of the first games known to take advantage of the new MFi (Made for iOS) game controller support Apple added to iOS 7.

Apple shared two hardware mock-ups with developers during a 45-minute long WWDC session called "Integrating with Game Controllers". One controller featured the "form-fitting" design 9to5Mac claims Crytek used during their demo, and the other was a wireless standalone device. 9to5Mac said players can use either touch-based navigation, or the D-pad and physical controller buttons to control the action in Crytek's new game.
