I have an iPhone 4s 16gb on 6.1.2. Today my wifi connection lost and I tried to connect for about 15 mins and then I reset my router, reset name, pass etc. Then I connected succesfully from my PC. After that I tried to connect with my 4s but it kept saying incorrect pass. I was sure that I was putting true password. I can't restore cause I want to jailbreak it soon and there is no way to restore to 6.1.2. Does anyone know how to fix it? P.S: I tried to reset connection settings, all settings etc. But it didn't work.
