Hi.... So, I have a seen a number of posters talk about doing a complete reinstall of the iPhone with 3.0 vs. an upgrade. The indication seemed to be that some were seeing better performance (e.g. less lag, etc...) if a clean install was done. My question is how does this get accomplished? I have done standard upgraddes only, and probably will tomorrow to benchmark things first. But, I would still like to understand how to do more of a clean install. Is this the same as a restore using the restore button in iTunes? Thank you.
