iOS 7 to shake up photo sharing, iRadio confirmed?

With just hours to go until the big WWDC event, speculation about what Apple's iOS 7 has in store is understandably at fever pitch.

While we think we may have had a glimpse at the anticipated new flat design, the Wall Street Journal is reporting a few new tidbits of information to add to the pot.

The new iOS will reported to bring "new ways to share photos and videos with other iPhone users" which would corroborate AirDrop integration, which will bring integrated sharing between Apple devices; not just iPhones but also iPads and Macs too.

The WSJ is also backing rumours of iRadio making its debut, adding that the Apple will announce the "long-expected streaming-music service", which it claims will be supported by Apple's iAd service and feature a "Buy" button for downloads.

Gruber says 'hold the iPhone'

According to prominent Apple blogger John Gruber, however, we might want to be a bit cautious about the leaked iOS information we've been picking up until now.

Speaking on this week's episode of The Talk Show podcast, he claimed that "all the leaks are wrong" regarding iOS 7 so far.

He also claimed that Apple's Jonathan Ive-developed OS overhaul will be "polarizing" according to what he's heard from friends in the know.

Gruber's words came before the WSJ report, and there's no way of knowing if he was talking about the actual pictures we've seen or the more general rumours about iOS 7 dropping the skeumorphic design.

The upshot? It's all still to play for. We'll know for sure in a few hours - WWDC kicks off at 10am PT / 6pm BST / 3am EST.
