I found one that works with Windows Mobile devices but don't know if it will work with the BB OS. Does anyone make one to work with the BB OS?

Just for reference this is what I found: hxxp://spectec.com.tw/products_detal.asp?dptype=w1sdw823

from what I read, wifi microsd cards are actually a bit longer than normal microsd cards so it prolly won't fit. This one might be different.
This is not the first microsd wifi card...
