Hello,

I bought an Iphone 4s when I went to U.S. Then because of my intense schedule, I could not find time to register my IMEI number and now I received a message that because of the reason that I have not registered my IMEI number, my phone is going to be blocked. Currently, I am not able to register it. Because according to what my telecommunication company said, I had to register it within the 31 days after I entered the country. But it has been about 8 months that I entered the country. Therefore no longer exists a legal way to register my IMEI number.

I started searching for ways of changing the IMEI number. It seems like there does not exist a software to do it. I do not know if it is because IMEI number is stored in a read only memory or because it is such a difficult operation and most of the hackers do not want to spend their time on this subject or because only I am not looking for the right place. Does there exist a software to change Iphone 4S' IMEI number?

If a software does not exist, then I think hardware hacking may be a solution to my problem. I predict that on the motherboard there must be something like a GSM module and if I change it, my IMEI number should change automatically. However I could not find anything regarding to this topic. Does anyone of you know anything about this topic?

And the last one is Gevey. I did not search much for it. But according to many comments I read, it is a buggy solution. There are many complains at the forums and the google groups about Gevey. Do you recommend me to give it a try anyway?

Any effort to help will be appreciated.

Regards,
Bachmann

Note: I know that changing IMEI number is illegal and all the responsibility belongs to me.

There is no legal way or software to change the imei number.
Gevey is no option for you. You need an active device for using Gevey.

Send an email direct to the telecommunication company where you've bought the 4s, maybe they can help...

I definitely meant to thank for TomMunich's post, not the OP. And now I can't figure out how to unthank . IMEI changing is illegal as the OP mentioned, and we do not allow the discussion of it on these forums. Closing thread as TomMunich's answer is correct. Contact either the carrier or the person you purchased the phone from.
