According to some sources, the release of the 3G iPhone is two months away, as the handset will be presented at Apple's Worldwide Developer Conference in June.
Apparently they will introduce three versions with different capacities, including 8GB ($399), 16GB ($499) and possibly a 32GB ($599) model, though this is yet to be confirmed.
In addition, the new iPhone will be 2.5mm thinner and will be made of a more "high-end" material. It will integrate an Infineon-based S-GOLD3H 3G chip that will deliver HSDPA non-U.S. speeds of up to 7.2Mbps.
That's pretty much all we know for now. Stay tuned for more details.
