The post has nothing to do with global warning so the thread name has been changed. Issues like this can be directed to Apple and if a problem the user can have the iPad replaced. There are issues with so call 4g world wide but at the end of the day it is complicated by different standards used. For example the new iPad does not support 4g in Australia however it is 40% faster on the 3G network than any previous iPad. To majority of users this is a plus. When we have more information regarding any resolvement of the issues we will inform you. Hope this helps.
