I purchased 3 4GB cards from this place -
Memory Stick
They have an ebay store with a great rep.
I have the cards for a few months now. All work fine, no problems with anything at all. I've used them to make MMS, play games, you name it.
I only found out recently that they are fake.
*shrug*
Who cares?
I got 3 for less than 30 bux shipped from china. That's all I cae about.
