How to unlock my iphone 4 which is not activated with original carrier?

I made a mistake by cancelling my Telus service without unlocking my iphone 4 which is locked with it now. Now they can't do it because it is no more active. Is there a third party solution to this?

You can unlock your iPhone 4 from Telus Network using Remote unlocking method. Which is the safe and secure method to unlock iPhone. You can get this service from http://www.classicunlocking.com/apple-iphone-4/rs16wp9/ here you need to specify your country, Network name to which it is locked, IMEI number of your iPhone. Here they unlock your iPhone using latest versions of iTunes.
