Slower. But manageable (typically 3-4 Mbps) -- just don't go to Bell.
not so good. Unless they updated their network in last 6 months or so. I used to get like ~600 kbps in my house, and maybe like 1.5 mbps in downtown area. When i went to toronto, i was getting close to 3 Mbps. However, Telus network is AWESOME here, i get like 5 Mbps here at my house, and at most places its between 2.5 - 5 Mbps. And their upload speeds are quite good as well.
But how would that work, if rogers, fido use a sim and bell and telus don't?
oh geez.. James, where have you been, Bell and Telus built a 3G HSPA network, how do you think they've been carrying/selling the iPhone 3G/3GS since November?
