A common misconception I see excusing AT&T's poor data performance is the belief that AT&T's network is expected to handle a lot more data than any of its competitors. That idea was disputed by a research firm saying that AT&T actually handles less raw data across its network than Sprint, and far less than Verizon. They attribute this claim to larger 3G footprints and the fact that Verizon and Sprint both have sold many more data cards and mifi devices than AT&T, and those are the true bandwidth consumers. http://www.zdnet.com/blog/gadgetrev...t-for-63-of-nations-mobile-data-traffic/13790 Another article came out today actually discussing data consumption specific to smartphones on Verizon, claiming that Verizon smartphone users burn on average more data than iPhone users on AT&T, to the turn of almost 100MB more per month. Interesting to see that the Android and other smartphone users on Verizon are using on average 421MB per month compared to the average 338MB per month being used on the iPhone. So far Verizon's network has held up to the massive growth pretty well, with no widespread reports of data congestion. Since Verizon separates their data and voice, increased data usage will have no effect on voice service like it does on AT&T. Now the question would be if Verizon were to get the iPhone would they be able to handle an additional several million customers who would leave AT&T. I believe Verizon is stubborn with their network and will find a way to cap the number of iPhones available by limiting their inventory should they start seeing decreased network performance. Also why am I posting this here? Because it's interesting to think about. I'm no fanboy to any carrier or phone and every time my contract is up I consider all phones across all networks before making a decision. I'm with Verizon now but in December when I'm out of contract if Sprint or even TMobile is offering something I like I'll jump on it.
