When the iPhone was unveiled, the mobile phone market was instantly changed. Consumers raced to buy them, and sales exceeded all expectation. The iPhone now dominates the mobile phone market. But what does this mean for mobile streaming?

Unfortunately, the current version of the iPhone does not support 3rd generation phone features such as higher data transfer rates that allow true streaming video to be viewed on compatible mobile phones. The good news is that a 3G version of the iPhone is in development, and is supposed to be available sometime in 2008. But for now, the iPhone is a device that downloads video only. If you want a viewer to see your video on their iPhone, they have to download it from their computer and load it onto the iPhone through iTunes.

If you do want to encode video for the iPhone, here are the requirements:

1) Codec must be MPEG-4 or H.264
2) Resolution can be up to 720×480 (but its actual display resolution is 480×320)
3) Frame-rate: 24fps

That’s it!
