There is a 4 GB SD card available. Anyway just to let you know I have the canon PowerShot a640 - I have used a 4GB MINI sd card with the adapter & a Micro SD card (8GB) no SDHC, and they work dont know why but hey cant complain right!
Most new 4GB and larger cards are SDHC cards (look on the card). Although they look exactly the same as a standard SD card, they are not. Unfortunately, there is no way that these cards will work with your camera, as it was designed before the SDHC format came out. As you've dsicovered, 2GB and less are standard SD cards, and will work with your camera.
There were a few standard 4GB cards produced a few years ago, most notably by ADATA (I have one that I use in my A620). Unfortunately, these are rare now, and are somewhat expensive if found on eBay.
