Toshiba fulfills your need for speed with UHS-I SDHC and microSDHC cards -- Engadget
I hope it works. SDHC cards can't be read in SD slots, so I am not sure that these new Toshiba cards will work in our SDHC slots. They extended the spec to include this so hopefully it is only a software upgrade away (if any upgrade is needed).
Honestly I don't understand why you'd need more than class 2-6 on a cell phone but that's just me.
