As expected, the phone looks roughly like the iPhone 3G which we all knew would be the case anyway since the high profile debacle surrounding the lost prototype (if you by any chance didn't already hear about this then check out our previous post on the topic). However, there are a number of significant changes under the bonnet which do distinguish the iPhone 4 as a significant step forward.

In short, the aluminosilicate glass (which is apparently up to 30 times stronger than plastic) promises greater durability and impressive performance in terms of minimising glare from bright lights and sunshine. The processor too will be upgraded to the same one that is found in the iPad (though running at a slightly lower speed), while the much publicised front camera will enhance video conferencing capabilities. On top of all this, there will be almost Wii-like movement sensors and also an impressive battery life of 300 hours standby time.

Anyway, for a more detailed breakdown of the current iPhone 4 specs, see Engadget's excellent preview; all that remains to be said at this early stage is that if you fancy investing in the biggest tech company in the world right now, do it soon, as it seems likely that shares which are already soaring (almost $260 each last time I checked) will rocket even more once the next generation iPhone hits the stores.
