Hi all, I've had my HTC Desire since last Thursday and this issue has driven me nuts. I even tried a factory reset but that didn't help. It seems that if I am on WiFi OR 3G my phone will work fine and will sync with the exchange server no problem. But if I switch from one to the other, it won't. Ie I am at home in the morning, works on WiFi, I leave for the office then it stops. I have to reset the phone by turning it off and back on again to get it to start working again. No changes in settings, just a reset. Ive tried all matter of things, re WiFi off, 3G on, leaving both on, changing the order I switch them on or off etc. Setting it to push email, manual check etc. The only thing that makes it work is a reset. Anyone else having an issue like this? Found any solutions or even other people having a similar issue?
