AT&T appears to be taking the network complaints to heart, as they're continuing the push to improve network conditions, particularly in densely populated areas.  According to a story by The Wall Street Journal, AT&T worked with Apple in 2009 to re-define how the iPhone connected to the carrier's network.  Thanks to the meetings between the two, the iPhone now uses fewer resources when seeking cell sites and checking for text messages.

With yesterday's WSJ story regarding Verizon Wireless getting a version of the iPhone, it's understandable that AT&T wants to improve network conditions to prevent a wave of cancellations.  To that end, they're spending $2 billion more on network enhancements this year than they did last year (2009), and continue to add and enhance cell sites as part of a 100-day improvement plan.

Despite the improvements, it appears that the battle of the networks will be in full swing this summer.  Will iPhone fans stay on AT&T, or migrate to Verizon?
