In time for Easter, there are many Jelly Bean updates rolling out this week. The MetroPCS Samsung Galaxy S III is getting updated too, along with the HTC One X and Droid RAZR/MAXX. Your Samsung Galaxy S III must be connected to Wi-Fi for the update to work.
The servers were so busy some owners had to wait to download the update. Be sure that your Samsung Galaxy S III is at least 50% charged. DO NOT STOP the process during the update, like we did with out AT&T model (see video).
