Engadget's reporting that we won't see just two new iPhones, not just three, but a whopping four next-generation iPhones coming soon!

we're hearing from a trusted source that new iPhones in 4GB, 8GB, 16GB, and 32GB capacities just garnered approval by the PCS Type Review Certification Board, the standards body responsible for certificating handsets for use with some carriers (AT&T, for instance).

Only a week remains before WWDC 2009, so we're deep behind crazy lines here, people, and anything is possible. But four new models? What about the CDMA version for China? The iPhone nano and iTablet for Verizon? The flying model that oinks?

We'll find out next Monday!
