We think alike...
I'm with Rogers. I'm happy with their service, I've been a Rogers wireless customer for 9 years now and I haven't had any complaints aside from paying slightly too much on a monthly basis. I can't remember the specifics of my plan, but I do have the $30 6GB data deal. Total is something like $85/month (inc. taxes, etc). I know I can negotiate a much better deal when my contract comes up (summer of 2011).
I am buying an unlocked iPhone 4 directly from the Apple store. I'm not going to take advantage of whatever "deals" Rogers will offer me. In one year, I will be through with my contract with them. At that time, I will re-evaluate the state of cell phone providers in my area (Toronto) and see what the best options are for me.
Now that I'm out of University and have a great job that pays well, I'm not too concerned with buying a full priced phone every once in a while. I can write it off on my business as a necessity (which it absolutely is) and still manage to keep up with Apple. I'm fairly sure they will continue to use a 1 year product cycle with the iPhone, meaning we have something new and exciting to look forward to each June/July!
