The iPhone 4 may be launching on all the major Canadian carriers tomorrow , but we're only just now starting to get the actual details on what they'll be offering. Rogers is the first out of the gate and, for a change, it looks like folks in the US may just be a tad jealous of their northern neighbors. It's not only offering the iPhone 4 for a further discounted price -- $159 for the 16GB and $269 for the 32GB on a three-year contract (for both new and existing customers eligible for a hardware upgrade) -- but it's bringing back its 6GB data plan for $30 a month as well. On top of that, Rogers is also offering a new iPad sharing plan that will let you share those 6GB between the two devices for an extra $20 a month. Still no official word from the other carriers, but MobileSyrup has turned up a leak that suggests Bell will be offering 6GB for $30 as well, and iPad sharing for just $10 a month -- although that's yet to be confirmed. We'll keep you posted as more plans are announced. Bell just flipped the switch , and their numbers are largely the same with one notable exception -- iPad data sharing is an additional $10 a month instead of $20, just as had been rumored. Thanks, everyone!
