After updating to IOS 5.0.1, my Factory Unlocked Iphone became LOCKED

I already purchased a FACTORY UNLOCKED IPhone 4 in Canada (MC604C) but when I update to IOS 5.0.1, it locked again.

As far as I know, when an Iphone is factory unlocked, it will be unlocked forever no matter how many times I update the version.

I called Apple. They admit that my IPhone was factory unlocked and assist me with some easy steps like putting in and out the sim card, turn off the phone, ect. But my IPhone still required a valid sim card from supported carrier to activate.

The point is, why do I need a valid sim card from Canadian carrier since my IPhone is factory unlocked and supposed to work with ANY SIM?

I asked Apple. They know the problem. They confirmed that this IPhone was factory unlocked and the only way for me is to CONTACT THE CARRIER WHICH PROVIDE THIS IPHONE. "If this was unlocked and now locked again, call the carrier to unlock it. Apple can't do it. You can't do it. Only the retail store or the carrier which provide Iphone 4 can so it". That's what he said.

But the point is I'm not in Canada now. My carrier was FIDO. And I have paid $50 to unlock it. Does it mean that I'll have to pay another $50 to get it unlocked again?

My old version before updating was 4.3.2, baseband 03.10.01.

Can anyone help me with this problem? Can someone in Canada call FIDO service to work this out for me? Please...

My serial is: 88118TSHDZZ

Thank you.

I paid $50 to unlock it. FIDO has this service. Before buying an Iphone here, they will ask if you want to buy an unlocked Iphone or buy with contract. If you want to use free sim, pay $50. That's it I've used it smoothly in Vietnam with any sim cards but unfortunately, when I update it to IOS 5.0.1, it was locked again.

Rogers will do this for $50 at the end of contract for iPhones, Fido (owned by Rogers) may offer this but I've yet to test it.

By checking the serial and IMEI, I think they would know that my Iphone was unlocked by their carrier. That's why I need your help by contacting FIDO:

- 611 free of charge from a Fido phone.
-1 888 481-3436 (FIDO) from any phone in Canada or the U.S (Free of charge).

Too bad if I have to pay another $50 to unlock it. It's even worse if my Iphone is locked forever if they don't help.

How did you purchase a FACTORY UNLOCKED iPhone, but then have to pay Fido to unlock your phone?

This boggles the mind.

Sorry because I can't distinguish between a factory unlocked and a carrier unlocked. I guess they were one. It was just Fido asked me if I want an unlocked Iphone or use with contract, I said I want an unlocked version. They charged me $50.

That's it. And now my Iphone was locked again.

I don't remember how much because it was years ago. Just remember $50 which switched my Iphone 4 from locked to unlocked. I bought it in Toronto, Ontario.

One of my friend told a funny story about FIDO. He's from Poland and had a locked Iphone 4 (used with Gevey sim). When he travelled to Canada he made a call to FIDO and meet a "noob" representator. After fooling around with her, he paid $50 to unlock his Iphone that he even didn't know where it came from (Of course its model is still from Canada - MC603C).

I bought this Iphone 4 from FIDO. I'm now using another black Iphone from Canada (MC603C) which my friend gave me on my birthday. Version: 4.3. Firmware: 04.10.01 and it works with ANY SIM CARD just like my Iphone above, too. I really want to update this black one to 5.0.1 but I'm afraid they will also lock it as they did with my white Iphone

Who unlocked your iPhone 4? A FIDO staff. How could I remember her name?
Was / is it jailbroken and the baseband modified? No. It wasn't jailbroken. I updated it to 5.0.1 via Itunes so the baseband is 04.11.08 now.
Did you buy it with a three year contract? No.
How much did you pay to opt out early? $50 to unlock Iphone with $xxx that I can't remember.
Was your account fully paid off before you had it unlocked? Yes. That's why I could use it smoothly when I came back to my country.
Do you have a receipt(s)? I didn't keep it
