Thanks everyone, some good tips for appz here too. As someone who has been known to ride with sandwich bags on the feet to keep warm i can see the logic of bags on phones. I went for s3 mini in the end, 15.50 for more time and texts than i can use plus 500mb data. Not sure how much data the maps will eat. And yes, do love the os maps too, but if i ever do manage the top to bottom ride that might be all my luggage!
