Like 3 years ago when it came out. This really is a lame excuse now. They already had significant, widespread congestion problems BEFORE the IPhone even came out. They simply didn't spend enough on upgrades even before it came out, skimped for years after it came out, and now are playing catchup for years of underinvestment.
And you know this how? ... by personal trivial experience? ...by stuff you read from people online or here? ... or have you actually looked at actual hard core system data?
