Sorry if this has been asked a million times, but I can't seem to find the answers. No doubt due to my ineptitude. Memory Questions: How much memory is std. internal? My phone says 123MB available. How can I upgrade from the std. memory (SD card) without losing my data? How large an SD card can I use in the Hero? How can I get MP3's onto the SD card? Do I have to sync with my PC? Can I load apps. to the SD card instead of the internal memory? Thanks in advance for humoring this complete novice.
