I used SPB for weeks. It is the biggest battery drain I've ever had on my phone. The day I stopped using it was the day my battery life came back up to normal. I still keep it to show off my phone every now and again, but I don't use it often, and keep it unistalled.
I will look at this when I get home, I just wanted to join this thread as to not forget. I have SPB 3D Shell and for as much as I like it, it has to go, they can keep the $14.99. Cute when I have 5 apps, now I have 60+, phone is slow, sometimes freezes complety............I like the look and feel, but functionallity is more important.
