Naa ko question, ka notice ko sa ako iPhone 4 (Jailbroken), if ever ireboot or off/on nako cya, after it boots up, dli na cya maka send/receive text messages and dli na sad cya maka make/receive ug calls... The fix tho is mu adto rako sa settings then I have to reset all settings (settings>general >reset > reset all settings) then after resetting, ma ulian na ang text and tawag and ma ok na cya... but the thing is, I always have to do that everytime ma off or ma reboot ako phone which is a hassle... naa na naka experience pud ani? ngano kaha na? my IOS is 5.0.1 pa.. knanglan kaha ko mu upgrade na? Any advice?
