im locked out of my iphone because i forgot its passcode. i have a computer that i am signed into my apple id with, but i never synced my iphone and computer. i figured out how to erase it through find my iphone on computer, but it says the erasure will only complete once the phone is connected to internet and it wont connect as i cant get into setting on my iphone since its locked. if anyone had any ideas as how to help it would be greatly appreciated tysm.
