Will there be a new iPhone?

I’m about to switch my mobile carrier and get a new phone, probably the 8 GB iPhone. But, knowing Apple, they’ll probably come out with something better in a month. Should I go through with this?

My service provider is crap, and they duped me into getting a horrible Samsung Instinct. Their customer service is horrible, if it even exists and everything is way to confusing. It’s Bell, by the way. I want to switch to Rogers. I do have to pay 450 dollar disactivation fee, but I feel like it’ll be worth it in the long run. The basic iPhone plan here in Canada is 60 dollars a month.
