Cisco, others want to offer mobile video chat, so why not Apple?

The new iPhone hardware expected to ship this summer from Apple Inc. is rumored to have a video chat capability supported by MMS, among other new features.

Today's roundup of rumors and speculation about the upcoming iPhone hardware also suggest that there will be a 32GB model, a boost from the current 8GB and 16GB models.

But the reports raise questions about why the iPhone doesn't have an expansion card slot for unlimited storage capability, especially if users will be storing massive amounts of video from video chats, video streams off YouTube or other places.
