Bell and Telus recently introduced competing promotions, offering the iPhone 3GS 8GB for precisely nothing with a three-year commitment. This presents an enticing opportunity for those willing to saddle up with Apple's last-gen phone for the long (long) haul, but really, is anyone still interested in actually doing so? With Telus, only refurbished models are available, and it appears to be an online exclusive for now. Meanwhile, Bell's promo features new (as in unused) 3GS', and should be available in stores. Nothing like watching a race to the bottom, eh?
