According to a churning rumor-mill, Apple desperately wants to make over-the-air downloads of iTunes content a reality on the 3G iPhone. Apparently, a record label executive "familiar with the discussions" states that the Cupertino gang is hoping for a "big launch in June" which includes OTA music downloads, ringtone sales, and ringback tones (the substitute music you hear instead of a ring when calling someone). There's only one problem: the labels want a higher premium for those services than a typical MP3 download. Of course, Apple's iTunes pricing has been a point of contention for some time, though its recent rule-bending for HBO could lead to upped charges for the new services. Something tells us Apple has the tenacity and bullheadedness to make this work -- let's just hope they can temper the labels' greed with the end user's economic realities.
