AT&T is at full capacity. They are maxed out. Their cell structure can't handle much more. Bottom line.
The problem is going to get worse before it gets better. I'm not a Apple fan boy but don't blame on Apple on this. The technology and consumer fascination in smart phones (iPhone) has out grown the ability for wireless carriers to keep up.
But the won't admit it, yet admit there is a problem.
I just walked into the downtown MPLS AT&T store, and fired up speed test and asked if this is what 3G is meant to be. The salestards (RT: @fakesteve) basically said... "Oh, it's an iPhone 4 problem... hold it different", "Call Apple Care", "Go to the Genius Bar", "Soft Reboot your Phone."
I stood my ground and asked if someone could show me the capacity map of downtown minneapolis. They stated that was confidential. They then stated there is a plan to increase bandwidth and capacity. I asked for due dates.... they said there were none, and I said, then, there is no plan.
I got escalated to a manager who was angry with me taking up his time fielding a technical issue... I asked him who I could get a face to face with within AT&T about this technical issue, and he said, 'no one.' He then spouted the same "we're putting a towers and cable backhaul everywhere... so I asked, and 'when will this be done in Mpls?' 'There is no date.' 'If no date, then when will capacity meet demand?' 'No idea.' 'so if there is no date for hard deliveries, and no date for meeting anticipated capacity, exactly _what_ is the plan?' (Angry bit lip look.)
AT&T can't manage itself out of this bandwidth crisis. They can't communicate a cogent plan (with cities, goals, deliverables and dates) to address this issue. There salesforce is overwhelmed and underqualified.
We need Verizon's LTE... Up the game and up the ante. I may not switch, but we need AT&T to realize they are not the only game in town, and when the iPhone goes, so goes a massive amount of their profits.
There is are only 3 things to networking... endpoint availability (coverage/towers), end to end capacity (pipes), and reliability. They are failing on at least 2 of those 3.
AT&T is thinking they are a mobile communications company... They don't realize that they are basically a 'final mile ISP' and if they can't deliver the above 3, someone else will, and no amount of 2 year lock in will save them 2.1 years after someone passes them on the information super highway.
