The Register has looked at a number of reports and rumors that together seem to hint at the possibility of Apple releasing a 4GB model of the iPhone next week at its Worldwide Developers Conference.
The first comes from Endgadget, which has a supposed leak from the PCS Type Review Certification Board, the group certifying GSM handsets, saying it has approved iPhones of 4GB, 8GB, 16GB, and 32GB capacities.
