Well I had previously been using iRealQuick SMS and liked it a lot but it was causing big problems. Mostly available memory. I deleted it for a while and last night decided to try it again. This time, by accident, I downloaded the first version. The only real feature I care about with iRealQuick is the ability to text in background. Some of the things I noticed right away- -The first version uses way less memory than the latest version. -Settings aren't as deep and complicated -Doesn't take up as much space as the latest version. I just wanted to share my experience with this and it might help someone else having difficulties with the latest version.
