yes sure (BTW fixed links are those:

I'm not sure how many Iranian users there might be @XDA forums but if this was a common problem I'm pretty sure those threads would be filled with loads of posts... Furthermore there haven't been any posts since December '11 / January '12 - most likely the problem either has been solved or doesn't appear to more than a hand full of ppl...
This: "its appear that ICS is unable to set right frequency when your sim card country isnt US or EU, odd thing, but common thing about us (people who have wifi issue with ics) is that we don't live in us or eu" sounds really too much vague and common to me as there are much more ppl living in Asia, Russia and Australia which wouldn't fall into "US or EU", too (although I'm not too sure about Russia).
Sorry, but the more I read and think about it the more I doubt that there might be an issue which is particularly related to non EU/US phones...
