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.
Another site, The Boy Genius, claims to have slides from a subsidiary of Rogers Communications, the large Canadian telecoms company. Among them is one of an Apple iPhone (4GB) available for $99 on a three-year contract, with video calling and a 2.0MP camera, although the site admits it’s "very far away from being able to confirm this information."
However, that seems to have a little more weight with the report that Apple has a contract with a Taiwanese that supplies 2.0MP camera lenses.
As The Register admits, it’s not a lot to go on. But more might be revealed next week.
