Friends, please help me out here! I just recently unlocked a phone I bought from a friend. When I got it unlocked, my phone worked perfectly until a few hours later, I noticed my phone said "No Service" and switched over to "Searching..." over and over again. Here are a couple things I've tried: 1. Turn on/off Airplane Mode 2. Reset Network Settings 3. Turn on/off Cellular Data/Roaming Data 4. Remove and inserted SIM card 5. Restarted my iPhone I heard about jailbreaking the phone to resolve the issue, but I don't think I want to do that unless that's my last resort. Relevant information: - The phone was locked to Telus before - Was working on the Bell Carrier for a while until this problem occurred - This is an iPhone 4 - Modem Firmware: 04.12.09 Thanks for your time! Cheer.
