Rogers continues to threaten to cut off “unlocked” iPhones even though Apple seems to be OK with it. In an notice they say, “At this time there are NO Provision to sell these units outright or to unlock and / or sell unlocked units.  Rogers has advised that units which are sold outright and / or unlocked will not be allowed on the network.” What that means in action is anybody’s guess.

In case your wondering they can tell what kind of phone you are using because the iPhone’s IMEI number identifies itself. International Mobile Equipment Identity or IMEI “is only used to identify the device, and has no permanent or semi-permanent relation to the subscriber. Instead, the subscriber is identified by transmission of an IMSI number, which is stored on a SIM card which can (in theory) be transferred to any handset.” – From Wikipedia. 

Further Rogers says:

“Unauthorized modification to iPhone

Your iPhone is restricted to use on the Rogers network, unless you are roaming. If you attempt to unlock your iPhone and use it on another network, it may become permanently unusable. Making unauthorized modifications to the software on your iPhone violates the iPhone software license agreement, and any resulting inability to use your iPhone is not covered under your iPhone’s warranty.”
