get iPhone 4 or wait till the 5 comes out, Iv had other smart phones but have been waste of money as I end up going back to apple iphones.
But.. the 4S fails against the current crop of smart phones quite badly! The SGS2 wipes the floor with it in most base specs.
which part of the spec it fails at? screensize? not everyone want a brick. processor speed? look again. edit: http://www.redmondpie.com/iphone-4s-vs.-iphone-4-vs.-galaxy-s-ii-the-ultimate-comparison/
