It's hardly been a secret that Apple's Jony Ive is exploring some more radical changes to iOS since taking the design reins for software in addition to hardware, but Bloomberg is now reporting some new details that paint a better picture of just what's going on in the lead-up to iOS 7. As previously reported, that includes what's sure to be iOS' biggest visual overhaul to date, with a decidedly more flat and minimalist design replacing Apple's current skeuomorphic tendencies. What's more, Bloomberg is also reporting that Ive is exploring "more dramatic changes" to the e-mail and calendar apps, and that he's "methodically" reviewing all the new designs himself to avoid a repeat of the Maps fiasco.
Also as previously rumoured, Bloomberg reports that Apple is pulling people from the Mac team to work on iOS in order to get it done in time, and that Ive has been encouraging collaboration between the software and hardware teams -- which, as Bloomberg notes, have previously been operating in separate silos. That all comes as Apple is apparently pushing things closer to the deadline than usual; while Bloomberg reports that iOS 7 is still on track for a release "as soon as September," internal testing dates are reportedly being set later than they have in the past, and the sweeping changes Ive has embarked on are said to have put Apple "at risk of falling behind." Of course, Apple does have one upcoming date that's now set in stone: WWDC on June 10th, when it has already promised to show off new versions of both iOS and OS X.
Update: All Things D is now offering its own confirmation of much of what Bloomberg is reporting, and quotes one source who describes iOS 7's new look as "de-glitzed."
