Updating unlocked iphone to 2 1
In fact, that’s only one of the results of installing updates.
The other important thing updates sometimes do is to bring patches or solutions to discovered vulnerabilities or bugs.
Be sure to turn your i Phone off first before you remove the SIM card.
If your i Phone does not show the signal bars in one location but works one in another, you’re most probably in a poorly covered area.I tried updating to 11.2.1 and 2.2 in hopes of solving the issue but neither had so I downgraded back to 11.2 in hopes of future help through jailbreaking my device.I have already contacted Apple and been through every possible set to restore service with them and my GSM provider (T-Mobile USA Prepaid).When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution.If you can, kindly include the exact error messages you are getting to give us an idea where to start.
Any ideas or suggestions on possible fixes would be greatly appreciated. When it comes to No Service issue on i Phones, there’s usually no universal fix.
