I know from personal experience that Charlene’s reception on her iPhone is less than stellar. Tech Crunch seems to have similar sentiments.
I’ve been unable to do a speedtest on my Blackberry as all of the web-based tests seem to require Flash. But based on my observations, it seems decently speedy. Granted, I’ve never tried to watch YouTube on it. As I mentioned before, I do wish it had WiFi, though. Oh well.
