Just a little warning to other users: I installed this app about two days ago and it was working perfectly. Today out of the blue, I plugged in to charge and received a message. Sms Box was only checked to back up old messages, as soon as I got the message it started to run. After that my phone became unresponsive and soon enough there were boot loops. The phone would start up, everything up and loaded then before I could do anything the Sms Box icon appeared on the top menu, boot loop once again. Battery pulls and nothing helped. I did a nandroid restore and tried to duplicate the problem again. Sure enough the same thing went down. Kind of weird, I have never seen an app that single handedly forced a restore.
