Wondering lol I need one but I have the extended battery. BTW the droid bionic is EXTREMELY light to me, lighter than my droid x. I really needed the extended battery for it to actually feel like a durable phone lol. But the build quality f this phone is fantastic, so don't get me wrong. Also, I played with it rooted + not rooted. Rooting it speeds the read and write times for me, just saying!
