[1.1.2 OTB] Stealth Sim Problem!
Ok so I have a 1.1.2 OTB phone, and I purchased a StealthSim to unlock it. I cut my sim, and put both my sim and stealth sim into the tray. It works fine, but at random times during the day I get a no service message for a while and then my carrier refreshes and my carrier is displayed again (FIDO carrier in Canada). I heard that on the 1.1.2 models, the phone refreshes the SIM every time your phone connects from tower to tower so I think this is what's causing the problem... Someone told me to update the lockdownd file, but I don't know what that is or how I can do that. This gets really annoying sometimes because if I'm talking on the phone it'll cut out sometimes. Please help me guys! Thanks in advance.
P.S. I live in Canada, and my carrier is FIDO. Someone said install iWorld, but I don't think that's ganna make a difference.
