[Q] Help unlocking s3 to metro pcs
I am alright with phones understand android a decent amount and computer as well. I worked at Radioshack for 3 years so know my way around most nondeveloper things on a phone. I need to edit my apn setting on my S3 to be able to use data on metropcs. Everything else works but data. I can not edit APN as it is just blanked out. Is there a way to just edit the apn settings without rooting or must I root the phone? If I have to root can I have step my step instructions for the easiest way to do it. A link to a thread would be fine.
Any help would greatly be appreciated.
