I have less than a month to decide if I want to keep my Sanyo Zio or trade it for this phone. NONE of the sprint stores around me have live phones, I called the mall and even they don't have this one live. So I'm wondering if anyone has any experience with this one, is it laggy? The zio is a little laggy, mainly when loading the home screen coming from certain apps or sometimes from sleep mode. Especially the widgets. I can live with it, but if the optimus S is faster I might exchange the zio for it.
