THREAD CLOSED!
XDA does not allow any kind of IMEI editing incl. discussions or tutorial about it. Even if this thread is not a tutorial it seems that the request will be used for a type of IMEI editing.
The only exceptions to this policy are discussions and tutorials about restoring original IMEI/EFS that's not considered editing/changing and spoofing/masking of IMEI on software level.
But as a general rule: NEVER ever give your IMEI to anybody - never ever!
