Citing industry sources, TG Daily is reporting that the 3G iPhone will launch at WWDC 2008 in June.
Apple will announce at least two models, an 8GB version and a 16GB version. Pricing is expected to be USD$399 and USD$499 respectively, making them the same price as the current iPhones. There is also a chance that a 32GB 3G iPhone for USD$599 could be announced.
The new iPhones will also be slightly thinner (about 2.5mm) than current models. The casing is also set to get a slight update to remove some of the “plasticky” feeling of some parts. Other than that, it will be unchanged (including the non-removable battery).
Should Apple release the 32GB iPhone, expect to also see a 64GB iPod touch to ensure that Apple continues to offer iPod touch models with twice the iPhone capacity as the same price point.
