I don't want to jailbreak my iPhone. I don't care for the new SMS tones. But I would loooove to overwrite existing tones. I DON'T want to jailbreak, can I still somehow log into the phone, and manually transfer some updated tones? If the phone has some kind of memory checksum, it might ... report an error of some sort (hope not). I can make ringtones myself, which is great, but I miss being able to change the SMS, email and calendar alert sounds.
