djh36 - it won't work because you're looking at the wrong size card. That's a full sdhc card. This phone takes minisdhc, or microsdhc with an adapter. The biggest size you'll find in a mini (check newegg.com) or micro is 8gb. 16 gb are supposed to come out soon, but I'd expect them to be twice that price when they finally arrive (they're overdue).
