Do I need to reboot my HTC Desire periodically?
I have had a similar problem but I also had my desire rebooting itself when using google maps. I spoke to vodafone who said return the device to us and we'll fix it, well I did and all they did was reflash it...total waste of time. Anyway ity started rebooting on its own again so I contacted HTC who were very helpful and said that on some desire handsets the motherboard was faulty and I need to send it to them for them to change the motherboard. I did this and 8 days later received my phone back and I have tested it with maps and all the app killer software and my phone works perfect. I say if you have any problems with any HTC contact them directly and they will sort it for you.
