Here is a confusing one. Apple has rejected the Sony reader app for iOS, so no Sony Reader for the iPhone, iPad or iPod touch. That's clear enough, but the reasoning behind lacks a bit of logic.According to Engadget, Apple has rejected the Sony reader app because it allows in-app purchases of content that don't go through the Apple infrastructure. Again, that's clear enough. So where does that leave the Amazon Kindle app?You see, there's not a great deal of difference between Amazon's Kindle app and the Sony Reader app and with Apple adamant that it will not allow apps that access content purchased through external content stores, you can see the glaring inaccuracy here. Maybe it's a new rule from Apple and as Amazon has already got a foot in the door, it's exempt from the ruling.Neither Apple or Amazon are offering any words on the subject, with Sony being conciliatory in its approach, describing the situation as 'an impasse' rather than a rejection, promising to seek 'other avenues to bring the Reader experience to Apple mobile devices.' If Reader is important to you, there's always an Android phone. Or the Sony Reader hardware, which is still available to buy. Or just sit, wait and hope.
