Lol mega fail answers. I think currently there is no way to soft reset your phone without going the long way of turning it off and turning it on again. Quite annoying I know, but you should not have to soft reset your phone much at all, if you do then there is a prob with software etc. I have only soft reset my phone maybe 2-3 times in the few weeks I have had it for.
But again I believe the question is:
Is there an app or some special way to soft reset the desire, without removing battery or without pressing and holding power button and selecting turn off, as both these methods simply turn the device off and are not actually resetting the device...
