There are quite a few threads waxing lyrical about the advantages of rooting your phone, I haven't heard too many people saying why you shouldn't do it. Are there any good reasons to not root your phone? Has anyone got any horror stories of rooting their phone and having heaps of trouble. I'd be interested to find out. My instinct is that by rooting your phone your essentially giving yourself admin permission on your phone. Whilst useful, I suspect that this comes with security risks. I've heard that some jailbroken iphones managed to pick up viruses.
