Just to clarify once more:

• SDHC doesn't have to mean full-size SD, there are micro-SD in SDHC format as well.
• As was said already, Nokia states 'up to' some size not because of technical issues, only because that's what they have tested (in other words, what's available at the time). Probably there's some lawyer somewhere who tell them to do so or something.
• As soon as there's SDHC support in the first place, and that support goes over 4GB, then there's no difference when you go to ever higher capacities, except for those mentioned: Possible problems of formatting FAT over 32GB in Windows, and the 2TB current limit of the SDHC 2.0.
• The known limits, or potential problems with SD cards are: > 1GB (old devices) > 1.5GB (some Palms. 2GB works, but can use only 1.5GB.) > 2GB. SDHC support. > 4GB. After that it's the (non-problem of) +32GB formatting, and the 2TB hard limit.

As you can see, with the 8GB support specified by Nokia we have already passed the critical limits - we're in the clear.

(BTW: If something works or not is not something decided by democratic voting.. )
