A tradition unlike any other: the 3G iPhone rumor on the Internet.
Today's rumor, courtesy of Daily Tech, actually has a fair amount of detail. According to what it heard from a little birdie, Apple plans to stick with the 8GB and 16GB options for the 3G iPhone, as well as the pricing for those models, and announce the new phones at the Worldwide Developers' Conference in early June.
The new iPhones, however, would be about 2.5 millimeters thinner than their predecessors, and have a slightly different exterior finish that's less "plasticky," according to Daily Tech. I'm not sure if "plasticky" is a word, but you get the drift. No changes are planned to the operating system or user interface, the report says, though you'll, of course, be able to download the iPhone 2.0 software in late June.
Daily Tech also says Apple plans to always have a capacity gap between the iPod Touch and the iPhone. Right now, a 32GB iPod Touch is available, but the iPhone carries no more than 16GB of memory. The philosophy going forward is to maintain that discrepancy as Apple increases the capacity of the devices, probably for differentiation reasons as much as technical ones.
