As others have said, this 8GB MicroSDHC card works with the Samsung Tocco (F480) mobile phone. I plugged my card in, turned the phone on, and it worked straight away. Although the documentation doesn't specify HC support, the fact the phone does allow up to 8GB (and you can only get > 4GB in SDHC, rather than standard SD format), implies that HC is supported.
No problems with inserting or removing the microSD card from the SD adapter, and didn't seem excessively fragile.
Comes with a nice little case too, for the card and adapter.
