Wow, thank you, I'll give it a try. I don't know why you think it would be too large to work. It works great, with the read/ write speed around 750kb/s. It's a 16gb sd card (sdhc) class 6. I got it off ebay for $70 just after christmas. Of course I am using the wm6 rom on my x50v, but there are sdhc patches for wm5. If I'm not allowed to post that I'm using a wm6 rom then I'm not and I lied, it's wm5.
