is there a way to modify the ringers that come stock with android? for instance, if i select the ringtone "standard 4", it sounds like a very basic ring.. but when you actually use it he pause between rings is ridiculously short and just makes the ringer completely obnoxious. is there a way to set how long the pause between rings is? if not, whats the best place to find a good basic/office type ringer? thanks!
