I'm a Kindle 3 3G user from China.A few days ago,my K3 can't find 3g network.I find that menu-setting-311 can solve the problem.One day later ,my k3 can't find 3g network again ,and 311 can't solve the problem, so I reset the kindle to factroy defaults,the problem was solved.Today my k3 can't find 3g again....I reset again.My k3 still can't find 3g network,and 311 is useless too。
sorry,my english is poor。Can anyone help me?
