Fido to Rogers iPhone 4 unlock question?

Hey guys so pretty soon I'm getting an iPhone 4 that's locked to Fido. The problem is I'm on Rogers. I know I can unlock it, but after I unlock it, will I still be able to access the internet, the app store and everything like that even though it's on a different network than it was previously locked to? I mean if you can't access data applications, you might as well not get an iPhone right? Also it's because I have a data plan with Rogers and I don't want it to go to waste. Thanks for your time guys.

f you get a proper and legit unlock then you will not face any problem..To unlock an iPhone the remote unlock service would be a better option because,you need not give your mobile to someone else nor do you have any chance to enter the wrong unlock codes.To get such an unlocking service for your iPhone 4 approach Theunlockspot.com and by submitting the country and network to which the mobile is locked to you will be able to remove the restriction from the respective network.This will be a permanent unlocking solution.
