Not me. I'm planning on swapping to an Android 4g type next month, but planning on staying with Att. If you check close, Att's network really IS faster than Verizon, not to mention that Att GSM network can handle voice and data at the same time, where as Verizon's GSM network can't. I know some people have issues with Att and dropped calls, but I haven't had any problems here in Atlanta. Also figure in all the people who are planning on leaving Att and running to Verizon since their network will be so much 'better' aren't realizing the fact that once 25% of Att's network is about to be added to Verizon's network, and just wait and see how fast Verizon customers start having problems, and with Att's network having 25% less users and data usage going through it, customers that stick with Att will be 10 times happier than those locked into 2 years with Verizon and let's not forget that Verizon has the highest cancellation charge of any of them.
Just my .02 worth...
