Can the HTC p3600 accept 4gb miniSD cards and if so which one would you recommend?

HTC have said that anything above 2gb isn't supported with this device however people have said that 4gb cards that have been formatted with a FAT32 file system have worked, we have tested and recommend using a SanDisk 2gb mini SD card with this device.

Most of electronics don't support such massive SD cards, only digital cameras, that's what i know

I have not seen any devices that accept such a massive SD card either, apart from digital cameras as you say.

I haven't either.

As a matter of fact, Walgreens has 2gig card for Digital Camera on sale this week.

For any camera?

I imagine so.

So Why exactly doesn't phone or certain phones don't allow anything over 2 gigs? considering the fact that most people would be using the internet, wouldn't you think that you would be able to use a bigger card?
