MobileContentToday reports that The Early Show is partnering with its new corporate cousin, CNET, to provide coverage of tomorrow’s iPhone 3G launch.

CBS tech correspondent Daniel Sieberg will be on-site waiting for the doors to open at the Apple Store on Fifth Avenue in Manhattan (the same plaza from which CBS’s morning show broadcasts) at 8:00 am. CNET.tv will have ongoing coverage from the store, while CNET editors Brian Cooley and Tom Merritt will take calls from viewers during a special edition of CNET Live on CNET.com.
