Now I have the iPad with 3G for nearly 2 months. I am having trouble using all the allowance there is with Optus Australia. I manage to use up only 2.2Gb of download and upload last month and that is with a lot of download of apps. By the way, apple does not allow me to download apps that more than 20Mb without logging into iTunes or Wifi. I watch YouTube I have to say once a day at most but even so I don't use up much. After 22 days in the 2nd month I only use up 600Mb of the 1.5Gb. The trend is that even on the lowest/cheapest plan. I am struggling. I guess I am asking anyone has an idea into usage of iPad and data allowance. I guess the US forum members here are on the unlimited plan and saying ... Don't care to me Thanks for your opinion in advance.
