When we mentioned that 16GB MicroSD cards were starting to appear online I could not find a RIM specification letting us know what sizes are supported by each OS. Viscafe kindly supplied us with a link to a RIM knowledgebase article detailing which OS supports what size. Did you know that OS 4.5.0.81 supports 8GB & 16GB cards??? It also confirms that the Bold supports 16GB cards.
From the knowledgebase article:
The following table lists BlackBerry Device Software versions and the supported media card size.
| BlackBerry Device Software | Media Card Size Limit |
| BlackBerry Device Software 4.2.0 | Up to 2 GB |
| BlackBerry Device Software 4.2.1 | Up to 4 GB |
| BlackBerry Device Software 4.2.2 | Up to 4 GB |
| BlackBerry Device Software 4.3.0 | Up to 8 GB |
|
BlackBerry Device Software 4.5.0
|
Up to 8 GB |
| BlackBerry Device Software 4.5.0.81 and above | Up to 16 GB |
| BlackBerry Device Software 4.6.0 | Up to 16 GB |
Media cards that use Secure Digital 2.0 (SD 2.0) flash memory format, MicroSDHC, can support data storage up to and above 2 GB.

Just a note, my 8820 with OS 4.2 supported my 8GB microSDHC card.

@Thomas: I’m not surprised its “supported” but did you confirm your BlackBerry saw all 8GB, because it might have only seen 4GB and you might not have noticed necessarily?

Maybe Thomas was aiming low. According to this BerryReview article http://www.berryreview.com/2007/07/18/blackberry-8820-specifications-released/
from July 2007 the 8820 supports up to 32GB.
