Do it yourself..........
ALL , repeat ALL the cellphone shops in POP use Blackra1n..............I have all my phones unlocked by myself and thought that maybe it would be worth it for me to see if there was a "better" way......not that Blackra1n isn't ok.....
I went to the shop mentioned, the Claro shop across from Codetel (where they sent me) and to one over near Caribe Tours.......ALL WOULD USE THE SAME PROGRAM...........so I just left them the way I had done it. I have unlocked 2g's 3g's and 3GS's........
This is the same free program that you can get yourself and put on your desktop and jailbreak / unlock your Iphone 3GS in less than 5 minutes........
Even though they may not charge you much in the store, sometimes the "unlock' and "jailbreak" fail and you have to do it again.........that would be a pain in the a** if you have to keep running back to them........
