I have 1 x HP 128MB SD card & 1 x 256MB Sandisk SD card and neither of them will install in any of 3 Ipaq 2210 pda's. I have upgraded to firmware 1.10 with SDIO patch 27102 from HP download site. I have spent 4.5 hrs on the phone with HP support and I am precisely going nowhere. I have tried both cards in Ipaq 19xx series, my HP digital camera and both cards work fine in eveything but the 2210's - HELP - would be appreciated. 2 of the 2210's are due to go to East Timor with a doctor within 48 hrs.
