I’m looking for a micro sd to upgrade my daughter’s celphone memory. I saw this Kingstons 4GB microSDHC while scouring the net, the card features a 4 speed rating which means it transfers data at a rate of 4MB/sec. to deliver optimum performance with devices that use microSDHC. The card comes with an added bonus of a Hooters calendar image or video for the cellphone. It can store more music, Hooters video, pictures, games and Hooters calendar. This memory card is a great buy, I think I’ll consider this one.
