This came to us via email from their PR staff:
Palm would appreciate help from customers to understand and isolate instances where Palm Tungsten T3 handhelds may not have recognized SD cards. Palm has received customer inquiries on this subject and is expediting resolution. To help Palm troubleshoot, we encourage users who have experienced this issue to provide the following information:
1. Manufacturer of your SD card.
2. Serial number of your SD card.
3. Last action performed with your SD card before the issue arose.
Palm is requesting users contact them through the T3 online support page, http://palmone.com/us/support/tungstent3/
