I just wanted to make it clear to fellow U.S. NsPro users. It is not illegal to swap a imei from one phone to another phone that are both in your legal possession in the United States. The last few years Congress has proposed legislation to prohibit this activity, but it always dies in committee. It was recentyly proposed again on April 25th of this year and sent to committee where it will most likely be tabled there again. See this link for the newly proposed legislation:
Text of H.R. 1730: Cell Phone Theft Prevention Act of 2013 (Introduced version) - GovTrack.us
The Cloning laws in the United States only apply to cloning sim cards or esn numbers. Because cloning sim cards and/or esn's can lead to subscriber fraud. Which means you can actually steal someone's service without paying for it while the true owner of the sim or esn is stuck with paying for your usage. With IMEI numbers that is not possible due to the fact that is controlled by the sim card in gsm devices, not the IMEI. And as a matter of law and fact, you can clone your own sim or esn from a device in your legal possession because in that situation there is no intent to commit fraud which the cloning laws aim to prevent.
I challenge any doubters to find a law in the U.S. that prohibits swapping IMEI numbers. And, after you come back empty handed, ask yourself this question. Why does congress year after year try to propose laws to prohibit IMEI swapping if it was already illegal???
