Nokia has teamed up with RealMedia to extend mobile streaming support on its series 60 phones. You may recall that RealOne is shipping on the newly announced Nokia 6600--it's part of the deal. The up-and-coming 3GPP format is supported, which is what QuickTime just got in its latest update.
This is good news for phone carriers... They are just itching to be able to charge their customers for more data usage. Streaming video is one of the most data intensive activities you could imagine on a mobile platform--it's going to be shoved down our throats.
