PosiMotion certainly announced this one well enough in advance (all the way back in December
), but it looks like its Helix gaming grip for the iPhone and iPod touch is now finally available, and at Best Buy no less. In case your memory needs to be jogged a bit, this $20 contraption promises to be ideal for "virtually any game," and let you use your iPhone or iPod touch in either portrait or landscape mode -- it'll also keep your headphones from getting tangled up for good measure. Still not convinced? Then perhaps the video after the break will change your mind -- chains not included.
