I have just went out and purchased the Sandisk 256MB+Wi-Fi card. After doing all of the necessary installation, when I try to change the network settings to "W lan" and select "details" to set it up it tells me it can not find the card.
Sandisk will not comment on whether or not it will work. The 7135 is not on the compatiblity list but other Palm devices are. I thought it was worth a try. Turns out to be a waste of money. Has anybody had any experience with this?
