I can find all sorts of Micro SDHC cards but the phone does not accept them.

Does anyone know of a web site or store where I might find a MicroSD card larger than 4 GB?

Thanks for any help you can provide.
Update: Phone does have MP3 capability. Went back to Verizon and the clerk tried his MicroSD HC 8GB card in my phone and it worked fine. So I can go with the 16GB SDHC cards.
Thanks to all for your help.
