If you updated your iPhone 3GS to 5.1.1 and it was previously unlocked with the 6.15.00 baseband, you probably noticed that it wont pick up signal anymore and it just says “searching…” and eventually “No Service” even if there is no sim card in the iPhone itself. Follow the steps in the video below to get your iPhone up and running in no time. Don’t worry, we at iHelpCorner.com know that some instructional videos are difficult to follow so we try to make every video as detailed as possible.
