Two more of Canada's larger mobile-phone carriers will now offer unlocking of the iPhone -- for a substantive fee -- joining with the largest three carriers in the country. The iPhones in question will still need to be off-contract, but can be carrier-unlocked for use in other GSM countries -- particularly the US, China, Mexico and other countries frequently visited by Canadians. This leaves only Koodoo, Sasktel and MTS (mostly regional carriers) as still not offering unlocking.
