HELP! my blackberry curve 8520 wont update to OS 5.0?

[Smoothercriminal]

i have version 4.6 and i want to uprgade to the newer version 5.0 but it always says there are no updates availble but i know there are because i know lots of people who have it. any help?
i have tried lots of things like,
updating my desktop manager to the lastest version
tried to update it on someone elses computer who has the update
downgrading to 4.5 (it then said that the only other update is 4.6)
re-installing desktop manager
and i have even taken it to the shop where i bought it to update it, the sent it off for 3 weeks and they said they couldnt update it so they gave me a new blackberry and this one wont update either.
i have literally tried EVERYTHING and nothing works?
i have also checked my carrier or whatever and they do have the update and i have the wireless plan or something like that so i can actually get the uprgade.
WTF IS WRONG WITH IT????

Perhaps your provider has not made OS v5.0 available yet.

Go here to check:

Click your provider then select 8520

maybe the country is set wrong? I don't know if this applies to BB but i had a nokia which didn't have an update on my country but when I set its firmware to another country, it would then find the update.
