SAM is a method that allows us to release our iPhone for use with any carrier. Those who now wanted to use an iPhonewith any carrier had three options: buy it free, pay an unlock by IMEI or use UltraSn0w . How many users getting the grant terminal operator were forced to pay the release by IMEIor use UltraSn0w. The problem is that UltraSn0w not work according to the baseband version of the device and the release by IMEI can be costly.
To resolve this setback can use SAM . A more complex method that allows us to use the SIM from any operator . To do this we must have done the Jailbreak to our device . So that we can access the repositories Bingner and retrieve packages SAM and SAM prefs.
The method is not as easy as using UltraSn0w . But surely that users who currently do not have a compliant baseband appreciate this option. Anyway, seeing as they are the phone companies and mobile subsidies is clear that now more than ever more worthwhile to buy a free iPhone .
Things that you need to unlock your iPhone using SAM: You need a jailbroken iPhone. If you haven’t done it yet then check out our How to Jailbreak webpage for links to the latest tutorial to jailbreak your iPhone.Latest version of iTunes and (of course) an internet connection.
