Hmm, you could be right in IMEI changing....
But i think, that´s possible with davinci client for 50€.
Yes it costs 50€, for that price i can unlock my phone....
But i want to say that i think it is possible....but not sure.

Does anybody have ICQ?
On the sheet there is the icq number from this autor.
Someone could ask him, if there are more codes availible.
