said by shaner:Cancelling a contract means you pay back the prorated amount of the discount you took on the phone when you got it.
That being said, most carriers offer a discount for BYOD phones, so the Nexus will be far cheaper for you in the long run.
Performance wise, the specs are very similar. There are plenty of head to head reviews on the net.
I have a six line corporate account, it's an entirely different can of worms. There won't be any discounts or anything because whatever phone I receive will be used on an already-existing line by merely swapping SIMs.
My current phone (an unlocked Note 2) will then be going to an employee who wants a phone with a big enough screen that he can look at without reading glasses, either to use with his own Telus account or with one of our corporate lines.
