  I noticed the same memory drain on my iPhone 0 (Verizon). SBSettings usually says I'm running ~000-000mb when only Mail and Phone are running. I installed this and used the default theme, and SBSettings showed me at ~00mb. I used RemoveBackground to clear out anything that might be running, then used "Process" in SBSettings "Free Up Memory" too and still couldn't get up over ~000mb. I set teh theme to "None", and have ~000mb available with only Mail and Phone running.  I love the concept, and I can't wait to see it fine tuned though. Keep up the good work!!!  I
