A regular client paid me a visit today. He owns almost every latest gadget, from iPhone 5, iPad, Blackberry z10, and just added a Samsung S III (sgh-t999) to his collection.
Like all his other gadgets, I have to either unlock, Jailbreak, Download applications, sync contacts and show him some tips on how to fully utilize them. Easy-breezy, but there was a problem, I've never Unlocked or Rooted a Samsung Android Device!
I turned to Google for help, and found several websites offering Unlock services for a Fee! all they require is the IEMI number of the device and Payment ranging from $3 to $30. I also found Several tutorials showing how to Root Samsung Galaxy, but the warning about the possibility of Bricking the device (rendering it useless) scared me.
Phone repair shops requested to do the unlock for 5000 Naira
Finally turned to YouTube and Found this Great Video Tutorial showing Exactly how to Unlock a Samsung Galaxy S III for free without the Unlock code or without Rooting it. Others might be looking for this, so I'm sharing it.
