Me too.
Strange, I have the same issue as of today (2g iPhone). Last night all I did was install the SMS notification for GriP.
As a side note, I've been extra conscious of my battery life as I've had activatesms2g installed and battery life has been horrendous. I couldn't uninstall it for some reason, so did a restore and set up as a new phone two nights ago. Chose to jailbreak with quickpwn instead of redsn0w to see if battery life would improve, and it was certainly better (compared with having activatesms2g installed) yesterday. Today at 9am I thought it was too good to be true (to have 100% of battery life left)!
