Performed the latest 4.3.1. JB on my Iphone 4, noticed that when I received the 2nd sms message using BiteSMS it would throw my phone into "safe mode". I am using the BiteSMS v.5.2 (pretty sure this is the latest). Was wondering if anyone else is seeing this? Not sure if this is an old issue or a new issue. I did do a google search but was not able to come up with much info on it. TIA!
