but these are not 'asics' in the sense we are usually referring to and you cannot use them as such, you can't make any sort of app which would pass apples approval process & it's not like you could even jailbreak your phone and access the engine from userland, you'd need a low level exploit from kernel, iboot or bootrom to try and talk with it in any meaningful way,,really you'd be limited to using main ap, jus compiled arm
Apple's not in the picture, for the reasons you describe (and others). It's Android-only for now.
The mobile SHA-256 chips are not in production cellphones yet - but they will be by the end of 2014.
The article linked to in the OP is what first alerted us that mobile mining could become more than just a pointless afterthought, thanks to these new chips. We have since confirmed (as best we can) that they will indeed be accessible and usable for mining.
article does not really say much, do you mean like airmont, cherry trail etc?
