Hi, Happy New Year. As a mistake, I put my girlfriend's number into the built-in blacklist. I went into settings > call > call rejection > black list, I removed her number and now she can call me. But the SMS are already blacklisted! If I open the built-in app "Messages" I find a red flag with the number of "blacklisted" sms. Other sms apps, like GOSms or Pansi couldn't read them. As I found around internet, I tried to put the SIM card into another phone: the incoming messages are delivered without problems, so it's a Galaxy S2 problem. I couldn't find a way to manage the built-in sms blacklist :-( Before I restore my smartphone from scratch... Any ideas? Thanks a lot!
