I am with Telus and have been for the past few years, only because they have the best deals on phones and the plans are remarkably cheap! The fact that Telus and Bell Mobility are going to be expanding from EV-DO and 1X and adopting the HSPA network is something they have needed to do for a long time! So many more doors will open to the consumers and from the manufacturers stand-point, easier!
Imagine a cell phone that can download/upload files just as fast or faster than your pc at home. Well, look no futhur. It has been mentioned in many places that the new network will be much faster and much more stable! Now implementing the new Voice-Over-IP technology and puting it into the palm of your hands! I know Skype and a few others have already done this, but, being able to do it 20Mps+ while driving to work, is a feat in itself! Currently the fastest network is topped out at 9.5mps and thats the absolute peek, the mere 20Mps+ is the minimum of the new 4G or LTE network!

So, for Telus and Bell to take on this new area, I think its a great idea and looking forward to getting onto this network! We shall see by 2010, if they can keep up to the GSM competition by becoming part of the 4G GSM Network!
