Hi. Thanks for the video. Is very helpful. However I havent upgrade my iphone 3g ios 4.1 bb 5.14.02 to the latest firmware. I'm worried I cant unlock it at the end. Any advice?

@mableow90 sorry mate the only way to unlock is baseband update!

i get all the way through but when i add the repo666ultrasn0w nothing happens help

[norwayee94]

In Cydia, It Says "ultrasn0w 1.2.3" not "ultrasn0w 1.2" Like It's Supposed To, Which May Be Why It's Not Letting The Phone Sim Unlock. I Need Help :/

@rickynike trata de restaurar al 4.2.1 original despues baja el redsn0w win 0.9.6b5 y solo escoje el unlock cydia nada mas porque ya tienes el baseband 6.15 que es el correcto para desbloquear para usar el iphone 3g/3gs para otra compana de telefono
