ArduinoWirelessShield 802.11 type B or G?

Hello,

Are there any wifi type B or G modules for this wireless shield(http://arduino.cc/en/Main/ArduinoWirelessShield). If so, do you know where I could by them?

Thanks,

These appear to be the same unit:

$45.99 802.11b http://www.cutedigi.com/wireless/wifi/fir-xbee-pin-compatible-wifi-drop-in-replacement-of-xbee.html

$45.99 802.11b http://www.junetrading.com/product_info.php?products_id=6887&language=en&cPath=31#googlebase

This one has a small antenna connector. Also available with a larger connector or on-board trace antenna.

$35.00 802.11b/g/n http://www.digikey.com/product-detail/en/XB24-WFUIT-001/602-1211-ND/2700945?WT.mc_id=PLA_2700945

They look like nice modules, particularly the type n XB24-WFUIT-001 from digikey, but I am not sure if they are compatible with the wireless shield. All the documentation that I see on the net about this shield talks about the 802.15.4 modules, see ref http://arduino.cc/en/Guide/ArduinoWirelessShieldS2. If it isn't compatible, I wonder if there is shield available. I particularly want to use the spi interface to communicate with Arduino.

Thanks,
