Hi,

I've never had a phone that can have expanded memory - planning to shortly.

Yes I know there is a difference between SD and SDHC, and mSD and mSDHC.

My first camera I bought when the max memory card available was about 128mb, and it still worked with a 2gb SD card, because 2GB was the theoretical limit of the SD card system (my understanding put in a brief way).

So...
If the Micro SDHC theoretical maximum is 32gb (I think thats what it is... the exact number is unimportant) why do each of the flasher cellphones state they are SDHC compatable UPTO 8GB?? I know the 16g has not been released yet, but does this mean that if I buy a phone now, it wont be compatable with 16gb or higher capacity cards?

Those oh you with ipods might agree 8gb is only just not enough, but with 16gb you can make do!

anyway...
can anyone explain to me whether the phones will be compatable with future cards or not? I'm hoping the stated limit of 8gb is just the marketing team covering their asses

Quick google search and found this..

If you go for a phone that supports High Capacity Memory MicroSD Card you should be right..
There are reports that the Nokia N95 will support 16gb MircoSD

Any MicroSDHC that is 4GB or larger will be High Capacity model.

My last couple of Nokias have stated 2GB microSD as their maximum but have run 8GB microSDHC without any issues, not a guarantee as cards get bigger but more proof that the stated max isn't necessarily the actual max.

Manufacturers usually won't state that it can read upto the likes of 16/32GB as they usually haven't had a chance to test cards that size in all firmware variants.

More often than not the handset WILL read the card but not always read it in a satisfactory manner. (for example the handset may slow to a crawl while it trys to read the 32GB of information)

I've had plenty of cases where the handset only officially supports 2GB but will quite happily read an 8GB card, the 5310 was one of these handsets more recently, also N95 classic.

As stated, its merely that the higher capacities aren't out yet, so manufacturers are not going on the record to say they work. I know the latest N-Series phones will, I know some trusty sources around a few mobile phone forums who test for Sandisk and they confirm 16 and 32GB are working for N95.
