Tomorrow is the big day, with WWDC 2009 kicking off and Apple getting ready to announce the next-gen iPhone and hopefully a netbook. Till then, we’ve got an ultra-thin iPhone concept on our hands, probably the last next-gen design we’ll be seeing before the real thing.

It’s actually a pretty hot piece of gadgetry, but it’s very unlikely that the device launched tomorrow will look anything like this.

The touchscreen looks a tad larger than the one on the average iPhone and I wonder how much battery life would such a thin handset provide… It may sound weird, but an ultra-slim phone like this is very likely to be dropped, specially if it’s glossy, as it tends to become slippery.
