It was tested that Nokia N9 can dual boot Android 4.0 and Meego, need some tweaks.

Is it possible that we can easily install 2 or more OS in mobile phone next time, so that we can choose alternatively the OS we want at different time?

Not interested?

Sure we are....but if there are no answers, what are you gonna go...

By the way, please dont bump...it will not speed things up...

I'm not an expert to the matter at hand, but in my humble opinion, a phone is not a PC in that you may not be able to install something grub-like where you can choose your OS. At least, I dont think phones are there just yet...

Besides, what would be the use to an alternate OS on a phone?

Better/more network tools and more (user-)freedom

If one OS is better than the other, why not just use the better OS? While there is the possibility that one OS has better tools , and the other has a 'better' (whatever that means) GUI, if you are just running two OSs 'because its cool', remember that while you are switching from one OS to another (and reboots for mobile phones can be irritatingly time-consuming) you can loose calls and texts that come in while the phone is unavailable (technically, you shouldn't loose the texts, but buffering of texts isn't particularly sophisticated, and if they don't deliver immediately, they can be heavily delayed, and a heavily delayed text may be as good as lost).

While I agree with your "because its cool" part, how is this different from dual booting Linux/BSD + Windows on an intel/AMD pc?

In my case, I really do need a second OS to connect with some wifi hotspots in Antwerp.
Neither Android or iOS are compatible with them.

The missing messages part.

The PC dual boot has the same limitations here (and more).

Perhaps your provider is just plain bad?
I can easily recover any text if it would get lost between provider (server) and client.

just because I want to use android and windows phone as well.
dual boot is better than using 2 phones.

It would be nice if the Linux developers came up with something that worked as Android does but had the feel and freedom of a Linux distro.

I thought Nokia did that and it killed them?

I'm not sure. I'll do some checking and see what I come up with. What I'm saying is a Linux OS would look awesome on a phone but it wouldn't have the functionality of Android or another program for mobile phones. I don't know of any entirely Linux based mobile phone system right now, but I will do some checking.

I was referring to this debacle. I never ended up with a Nokia Linux device because first they didn't have a data connection, then they didn't have a keyboard, then I ran out of money just before they died.

The link is representative, google if you want more information.

These are just a few of the sites I found that sort of explain it and show a few Linux based phones

This site I just found while searching for the Linux Mobile OS and I thought it was a cool idea, I'm sure alot of you have heard of it but for those who havent

Sadly they're all now dead (at least as far as I can tell).
The problem with Linux on phones is the same as it is on desktops -- most people don't like freedom, they like easy-to-use and locked-down.
I hope I'm wrong but I think Canonical's Linux device[s], if and when they materialise, will be no-root-access locked boot-loader and about as configurable as Android. Let's not forget that Unity with its "lets hide everything that might mean people have to think" mentality is at the forefront of Linux on the desktop right now.
I ought to point out I'm not as negative as the above may sound, but I'm resigned to the fact that open Linux (i.e. user has root access) will always be a niche thing. I can live with it but it makes me sad also.
