There has been some debate in recent days as to whether all four (or more!) 2009 iDevices which have been hinted at with multiple references in the code of iPhone OS 3.0 as well as countless published rumor-mongering reports and our own conversations with sources, will actually be announced -- no less ship -- at the World Wide Developer Conference next month.There is plenty of room for debate on the larger question, but when it comes to at least two distinct 2009 iPhone models ($99 8GB entry-level and $199/$299 16/32GB high-end models?), Rumors is very confident that we'll be seeing them during the keynote address on June 8th.
