Screen replaced - small SIM issue
Just a small question. Now I've done 2 screen replacements on an iPhone 4S I everytime have a small issue with the SIM card.
When powering on the iPhone 4S after screen replacement, it doesn't ask for a PIN code. It doesn't give the "no sim" error either.
Solution I found was to reset network settings or do a restore... both worked.
Could anyone explain me why this is, and what's the correct fix to the issue?
