Eye-Fi SD cards that add Wi-Fi to any digital camera now hold 4GB instead of 2 GB and can upload both photos and videos to YouTube and Flickr.
Eye-Fi’s limited edition 4GB card has now become the standard 4GB $100 model, and they’ve added a cheaper 4GB model ($80) without geotagging. Eye-Fi says they’ll be available today (March 3rd).

The 4GB Explore Video SDCard ($100):
Automatically geotags photos and videos; also offers hotspot access at more than 10,000+ Wi-Fi locations. -
4GB Share Video SDCard ($80):
Sends photo/video to the Web and your home computer.
Eye-Fi’s wireless SD memory cards let users upload photos and video automatically through Wi-Fi networks, although only the 4GB cards can upload video. Eye-Fi also has a deal with more than 10,000 Wayport and open hotspot locations across the U.S.
The original 2GB Eye-Fi cards now start at $50 (but don’t do the video upload trick).
