Not compatible with HTC Desire
I bought this card as a memory upgrade for my HTC Desire. Initially the card worked, with quite a slow read speed, but it worked. After a couple of weeks I found accessing media on my phone quite glitchy, sometimes my photos wouldn't be there and apps that were stored on the card wouldn't open. Then my phone began crashing, and when rebooted the SD card was mounted as 'read only'. No amount of rebooting and reformatting helped. It is not a problem with my phone because there are no problems when I tried using my old 4gb card that came with the phone.
Maybe this card will be ok for other devices, but HTC or other android users be wary.
