As previous poster mentioned, the 16GB microSDHC cards are available. I've found that the higher capacity micro cards generally (trial and error is the rule of thumb) work in most devices, especially if SDHC is listed. My 16GB card is working quite nicely in my Sirius Stiletto 2. And as ScottC said above, if it doesn't work, at worst you're only out a few bucks for the 4 and 8GB cards, and not much more for the 16GB (I paid $60).

If you have access to cards of friends or associates try them out. My Samsung SGH-A837 manual said it would take up to 4GB micro SDHC but would accept SANDISK brand 8GB.

Also some MicroSD cards are bundled withan SD format holder while others come with a USB device that you can put it in for use on other systems without MicroSD.

If your computer won't read microSDHC, look for a driver update to fix it. That's all I needed.

And it doesn't admit to the existence of my phone.

Heh. Day after tomorrow they'll have 16Gb, if they don't already!

Edited to add: they already do.

64GB SD card?
 

I am currently using 8GB cards.
I got curious while reading this thread and searched/found this:

MB, not GB. Big difference ;)

You lost a few zeroes there.

I haven't seen anything beyond 16gb in SDHC, let alone microSDHC.

I agree, this is a cool site, but for my phone (Blackberry Curve 8320) it doesn't list the maximum GB card accepted, it just says that it takes microSD cards.

It depends on the OS you're running. I OS 4.2 is limited to 4 GB, and newer versions can do 8 GB.
