Not to hijack this thread (even though it's pretty much dead) but no, I haven't. I started to, with iRealSMS. I did a respring after doing it to just that app, and the phone gotall screwey. I lost my netork on wifi, and it didn't want to let me reset it. I got it working, but with as much time as I spent getting it working again I figure I'll just wait a bit. If SB gets it set up with a script, then I'll use that, but if not, then I'll do it manually.
