| What is this lock and what happens?
SP Lock stands for a code your service provider put in your phone to
prevent the ability to use this phone with a SIM Card different than the one
you purchased it with.
This is due to a commercial trick: usually, Service
Providers sell phones and SIM cards togheter at a lower price than the phone
itself because they will earn from your telephone bill the money they not
charged you on the phone. Well, it's easy to understand they are not very happy
to let you spend such money with a different provider.
If you ask a Service
Provider to unlock your phone, it will ask you some money to cover the income
it will not earn from you.
The code your Service Provider uses to lock the phone may be
freely selected and so, theoretically, there is no software which may calculate
it. In practice, they often use an algorithm to obtain a different code for
each phone from their international code and phones IMEI number (which are both
unique), to avoid the case of duplicate codes.
However the code is stored in memory and may be read with
the right equipment and knowledge.
At very first, you need a PC and an interface to connect
your phone with it; second you need to know the memory map of your phone (each
phone's model has its own); now you're ready to make a dump of the EPROM of
your phone and read there the code you are looking for.
Little by little we'll collect info about the above
mentioned interface or memory maps, we'll add them to the page of the phone it
