Thanks for sharing this Simon! I also have the same phone and I really like the phone. Actually it is more than I need. I just bought it because I had an older Samsung Centura I got from Tracfone where I just paid for the minutes I used and it tripled the minutes, txt and data and it worked for me as me paying for the services like that was dirt cheap and all I needed until the phone wore out and kept freezing up so I decided to get an updated phone, the S3 not on unlimited talk and txt for $45 a month (plus all the extra taxes, fees, etc.). I still have my old Tracfone and it works; I just haven't added any more minutes on it.
