Going from a blackberry to iphone?

I currently have a blackberry bold 9900 that I got a little less than a year ago. I'm with telus and I have a 3year plan that I agreed to. My plan is unlimited social networking, Wi-Fi, bbm, unlimited texting and 200 minutes a month + unlimited after 6pm. I really want to upgrade to an iphone 5 but i'm not sure if I would be able to or if it would cost an extreme amount of money. I wouldnt want to cancel my plan or get out of it but i would like to switch phones.anyone with experience or knowledge?

If you're not signing up to a new contract (which you should - your plan is garbage) the iphone will cost at least $600 US

Don't do it you gain nothing but alot of kiddy apps that you never use.hey its a phone use it like one and save your self alot of money

If you cancel your contract and get an iPhone with a new contract, then you will have to pay an early termination fee. If you get the iPhone without a plan, it's upwards of $600 [US]. But if you pay the ETF, then the ETF plus the iPhone is still less than that. There's no way to go about doing it unless you wait until your current contract with your current carrier expires. Still, 3 years contract? I thought a 2 year contract was oppressive!
