Like I said, Apple's flash memory products do not include mismatched memory modules. Correct me if I am wrong, but I don't think any other companies do, either. Perhaps it is the chipset limitation, perhaps doing so is more optimal, or perhaps it's just more cost effective that way... it just hasn't been done.
Come to think of it, all current Apple products (iPod shuffle, iPod nano, and iPhone) include single flash memory module so it won't work anyway (unless Apple decides to increase iPhone's footprint, which is extremely unlikely).
