I have had my Desire for just over a month now and still haven't worked out how to get the text message alert to repeat. I have my phone on silent/vibrate when I'm at work, and I have sometimes found that a text comes in while I'm away from my desk and I don't discover this until later. Or even when I've got the sound switched on I don't always notice it if I'm in a noisy environment, or maybe I don't feel the vibration in my pocket. My previous phones have always produced the alert tone/vibration every few minutes until I read the message. Can this be done with the Desire, and how?
