Have just taken delivery of my new ipad3, did a quick set up and was amazed to find that my bookmarks and tabs in safari have been transferred from my ipad1. Is this because I chose Cloud backup? If so how can I keep the browsing separate? The new ipad is 4g. I will not use it out of the house very much at all. I would like a sim card with a certain data allowance that does not run out each month. Does one exist? I live in the uk.
