forgive me if this has been talked about, but I know officially Palm says it supports 2GB and people have talked about using a 4Gb card and having success. I bought a 4GB card and have had no problem. My phone recognizes it as 4GB. I read one post where someone said he had a 4GB but it didnt recognize it as a 4GB. My phone does recognizes the correct size and have had no problem. But I did notice a constant crash with mvoice or the other voice recording program already on the treo. I realized after a while it was the card since it stopped after I took the card out. Anyone else with this problem? Thanks
