I have alerts from Orion and other products e-mail and text my phone. The problem is that I have no way of distinguishing an alert from any other text message or e-mail because iOS doesn't let you customize ringtones based on sender. I know I can have a separate ringtone for my VIP list, but there's already several people in that list. I've tried apps such as Mail Tones, but they're flaky. Does anybody know a way to distinguish network alerts from other traffic without having to look at the phone? The only way I can think of is to have a separate phone/pager for network alerts.
