How can I upgrade my BlackBerry OS and how do I unlock it before activating it?

I just received a BlackBerry Tour 9360 with no phone number on it. I know I need to activate it to get a phone number, but first I want to unlock it, so I can take it to a different carrier and update the software (OS) on it.

It’s currently running v4.7.1.53 and according to the BB website I can update it to OS 5. However, whenever I try to update the OS it says that the phone is up-to-date with v4.7.1.53 and instead invites me (the BlackBerry Desktop Software) to subscribe to a mailing list for updates for the BB Desktop Software, which makes no sense at all. How can I update my BB without the BlackBerry Desktop Software or BB website?

I know that I need a MEP code to unlock my phone and my web surfing and investigations have told me that I need to contact the current service provider and ask for the MEP code by giving them my IMEI code. Here is the problem: I can’t call the carrier’s cust. serv. because I don’t have a number with them and whenever I try to call I am greeted by a recording asking for my telephone number, which I don’t have. I already tried with a friend’s number, but then I was told that if I wasn’t asking for help for a device that is using that number they couldn’t help me at all. So how the F do I get the MEP code to unlock my BB without going through the original service provider?

I am currently looking at support forum but that thing is a mess.

Thanks for your help.

    Apparently it is possible to update the OS, but there are some difficulties. The OS you update to has to be compatible with your carrier, if it's not the update while still possible becomes more difficult and is possible your phone won't work forcing you to downgrade to a previous OS version.

    This is what I used:

    In the end I couln't upgrade my phone but I could unlock it.

    I actually spent 6 hours, looking for a site where I can get the MEP code for free and finally found it:

    You need to provide them with as much info as you can about the phone, but you never give private or personal information out except your email address after which you will have to wait for about 24 hours for a mail with your code. I don't have my BB phone with me at the moment, but I'll post the results once I try to unlock it.

    I am still trying to upgrade the OS, so any info is appreciated.
