ZTE Blade/San Francisco memory cards that work I'm looking out to extend the card memory for my ZTE Blade phone.

Can anybody who has experience with this tell me which SD cards (preferably 16GB and above) certainly work well for the San Francisco/ZTE Blade phone? If you're using this phone with an SD card model that works, please tell me which one.

Note: many people seem to report that some SD cards do not work well with this phone.

Thanks!
I found this discussion at MoDaCo about the issue.  It includes cards that people have tried and found to work.

The generally consensus seems to be that Sandisk 16 GB Class 2 cards work.  Kingston 16 GB Class 4 worked for a couple people, but not for another until they tried deleting everything on it via Windows XP.  I personally wouldn't go lower than a Class 4 card, and I'm partial to Kingston.
