Not long ago, we told you about iControlPad: a case (of sorts) which adds a couple of Gameboy-style buttons to your iPhone, along with additional battery life. The device isn’t available yet, but it will be released very soon. And, hot on its heels, will be a very similar device which was announced some time ago, dubbed “GameBone.”

GameBone does the same thing iControlPad does. It houses your iPhone while adding a couple of buttons for gaming, and additional battery life. However, from what we’ve seen of GameBone’s site, this device appears to be so much better. Indeed, a recently updated list of features has confirmed this suspicion.

Here’s what you can expect from the GameBone controller once it’s released:

  • 8-way D-pad (directional pad)
  • 4 action buttons
  • 2 shoulder buttons
  • Built-in 1600 mAh Lithium battery for additional power for your iPod touch / iPhone
  • Rear button and LED to check charging state and capacity
  • Built-in stereo speakers
  • Omnidirectional MIC
  • 3.5 audio headphone jack
  • Rear kickstand
  • Volume control
  • Charge and sync ability*
  • Interchangeable core for compatibility with iPod Touch, iPhone and iPad devices
  • “Made for iPod”, “Made for iPhone” and “Made for iPad” certification**

* Supports all iDevices except for iPad charging
** Pending Apple’s approval

Sounds pretty cool, right? Certain aspects of GameBone really make it stand out from its competition. I love the idea of a built-in kickstand and volume control. And, the device’s “interchangeable core” for universality is a brilliant idea.

Currently, the company behind GameBone (22Moo) is just adding the finishing touches to the device’s internals. They plan to announce an availability date around October, so check back with us for updates on the device.

In the meantime, be sure to check out the gallery of GameBone pics below, or take a look (and register for more info) at 22Moo’s website. And, if you’re planning on investing in GameBone or iControlPad, be sure to let us know which one in the comments below!
