To all ppl with "simple solutions":
Thanks for your opinions. Since they are not reasonable, I don't have to discuss anything about this And.. No thanks, I'll keep using Internet and GSM. I know %100 privacy is not possible nor guaranteed, but doing my best is better than doing nothing. So there's no "false feeling of anonymity" when it comes to me. Maybe you should consider your motives about not letting other ppl hack their devices as they wish.

You sir, are terribly wrong =) Personal ideas are personal, and most of people (including me) do not care. Since this thread is named "Is changing IMEI possible?" it's a simple yes/no question with a hidden question "If It's possible, how to do it?" So its not a discussion of WHY, it is a discussion of HOW. It's a technical discussion, not a moral one.

You think It's not good to change it, or you dont want to change it? It is ok. Do not use this thread. Hey, I have seen another thread with some guy asking about pr0n on N900. It's funny!! But please, do not force your opinions or viewpoints on other people.

Sharing information and applying that information are not the same. Even if some people stole devices and change IMEI because of it, there's other users just want to change it because of anonymity, or just for fun, etc. Computers are more open than gaming consoles, and you see, lots of ppl pirating software. So what? We should make them more closed? So they can't pirate software, or if we close all torrent trackers, It'll affect pirates?

It is just.. weird to see that kind of solutions on a GNU/Linux distro's forum.

BTW, most of you guys already know that, but: If you steal a device, you can sell it, or find someone with enough knowledge and hardware to change it's IMEI number for you. They are already doing that for years, so It's possible for some ppl, but I don't know if it's possible on N900, how they do it and if it's possible with on-the-fly patching software, instead of some hardware and tools. (which WAS the main topic of this thread, long time ago)
