My iphone 3gs won't activate?

I had just updated a jailbroken(probably) and unlocked iphone 3gs to IOS 4.1 to 6.0.1. After the update, it wont activate. Any help would be great. I hope this can be fixed. Thanks.

Added (1). When I try to activate it trough iTunes, it says, " We could not activate your iPhone at the moment etc. " and when i use Wi-Fi, it says, " Your iPhone cannot be activated because the activation server is temporarily unavailable." I also got a SIM card that I used to use at the Philippines, but now I have migrated to Canada, which makes the SIM unusable.

First make sure your sim car can be usable with the iPhone. If not keep the sim car in the iPhone while youre restoring.

There is no jailbreaking & unlocking solution for OS 6.0.1. Factory Unlock is only method to use it with other networks Sim cards.
