I just became a new member here. I am having trouble with my iPad. My 3G stopped working. I have checked my remaining data and there is still 125mb left. I am unable to get it going again. I tried resetting network settings and stilno connection. Fortunately, my wifi is working but tomorrow I am going were there is no wifi. I am currently in Madrid Spain where there should be good 3G connection via AT&T but nothing.
