Morning guys, Slighty unrelated topic but would like to gather everyone's opinions on the new Galaxy 4. I currently have an iPhone 4S which has served me very well but I'm due an upgrade - either I can get the S4 at the end of the month or I can take out a cheaper rolling contract and wait for the new iPhone? Anyone have any experience with both iOS and Android? In addition, I was wondering if I should change network - I'm currently on Vodafone. Cheers guys.
