All 4GB Cards are SDHC so yes, this card should work fine for you.If not, we will allow you to return it for a refund.
Your Nokia 6500 Slide is compatible with the following memory cards:
MU-37 Nokia 2GB Micro SD cardMU-41 Nokia 4GB MicroSDHC Card
Kindly note that Nokia has not tested this 8GB MicroSD card with the Nokia 6500 Slide. Therefore, we are not able to determine if the 8GB MicroSD card would work with your phone.
So bottom line seems to be 4GB SDHC is OK
Thanks to all
Still looking for the clip to hold the card in place though if anyone can help.
