Problems with iphone 4 after updating it?
I just updated my iphone 4 to iOS 6 but when i connected it to itunes it says that the sim card is missing. Now i can't use my phone. What is wrong?
Put the phone in Airplane Mode, power it off, take out the SIM card, and leave it out overnight. In the morning, put the SIM card back in, turn the iPhone on, and turn Airplane Mode off.
This happened to me and I fixed it this way.
If this doesn't work, take it to an Apple Store.
- Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
- Why is my iPhone acting weird after updating it? When I'm using 3G and I search for something on google or try to open a link from my Facebook app, I get a message that says "Response Error. Technical description: 502 Bad Gateway - Response Error, a bad response was received from another proxy server or the destination origin server." What the hell does that mean?
