not to mention it is illegal .
Thank you!!
Let's look at the whole deal -
Cloning a phone id is illegal and most of the cookbooks telling how to do this revolve around that.
There's a federal ruling now allowing unlocking (owned) phones from carriers but all of the language is directed at GSM technology (the majority), leaving room for some on-going fights from Sprint.
In theory, you can take a donor phone and legally transfer its identity to the target phone - and you have to restrict capabilities to that provided by the donor and then safeguard the donor from use for the life of the target (so you can prove that you did a transfer rather than a clone).
Your problems here go like this from this point -
First, Boost and VM are owned by Sprint - if they ever catch you, be prepared for grief forever trying to get service from any of them.
Secondly, there are a number of sites helping with this - in four years, I've only found one legal one and it's under an injunction to stop until all of this is sorted out. And I hope I don't have to spell out how much you don't want to do business with an illegal operation.
Third, if you can find a cookbook strictly following every nuance of a transfer, if you get a complaint, mods are obliged to stop things and make an assessment. We're not all in agreement on this because a) we're not lawyers and b) even the lawyers don't agree. Don't expect a fair assessment even if you're right - we're not lawyers and we will err on the side of caution.
Fourth, if you post about a cookbook that details cloning, even if you don't mean to, then you're posting about things that aide and abet the criminal phone theft industry and mods will go all hard core on this - leaving such things alone makes our forums either a potential accessory to crime or an accessory after the fact. Either way, we'll be having none of it.
So there are your guidelines and constraints - please proceed with extreme caution.
On a personal note - I think that the carriers are wrong to control your phone use like this.
However - the law comes first, I am not a lawyer, and even if I were, I am not your lawyer.
On a final note - if you do find the instructions you're going to discover that it takes a LOT of steps to accomplish this, it's far from playing with the build.prop, and your opportunities for bricking your phone are real and really easy to do.
Nothing in this path is attractive or safe but you do what you think best.
