djh36,

IF you didn't notice that you can't use a micro without an adapter, you may not have the IQ to use this phone. That said, you can get an adapter from Meritline for about $4 shipped.

Micro SDHC is the format with the most compatibility that you can use on this phone. That means you're more likely to pull it out and use it on a camera, mp3 player, etc. down the road. BUT if you're only going to use the card for this phone - then you can save about $20 by buying the Patriot mini SD for $35 on Newegg.com. Otherwise, $55 for an Adata micro SDHC card might be your best bet. Choose wisely.

If you get a Sandisk card, make sure you get it from a reputable site - because they're pirated all over. Piracy for 8gb micros is sooo common it's ridiculous.
