Hi, I've installed iOS 5 on my iPad and iPhone, conquered transferring mobile to iCloud. One question remains! ONe thing still puzzles me, custome sms tones, I've had custome ring tones for quite some time and I'm familiar with the requirements ie less than 40s! When I updated to ios 5 some (3) of my ringer tomes were also selectable as SMS tones, I've since made 4 SMS tones but only 1is selectable, they all appear in iTunes under ringer tones. Does anyone's know the file or sound requirements/specifications for a custom SMS tones on ios 5?
