I've had a Blackberry Pearl 8110 through AT&T for nearly a year, but until now I haven't given much thought to using it's music player to replace my iPod. But, with the fact that my 4GB iPod Nano is constantly full and leaving me with no room for new music, I've started looking at my options. So, my question is, how big of a MicroSD can it handle? I've currently got a 2GB MicroSD in it for music and photos, but if it can manage at least an 8GB MicroSD, I'll switch to that instead of buying a newer, bigger iPod.
