Actually I got rid of a LOT of stuff in WB to get some more memory back. It seems to have worked pretty well. I actually have the stock icons at the moment. So, no current theme is even on my phone.
For some reason or another themes don't get along with my phone. 😱
I try to incorporate all my changes into a single theme or, if that's not possible, drop my mods directly into the folders on iPhone where they go (of course saving a copy of the original files before overwriting them with my changed files).
As stated, fewer items running in WB, makes me feel better.
