Torn between the 3 and 4. I'm just wondering if 1: the 4 gets faster 4G speeds?2: would it connect to wifi better over the 3? I don't have wifi where I live so I have to download my podcasts and other media files on weak public wifi connecrions(starbucks,wendys). Would the 4 be faster than the 3 in that area or no because they are both 802.11 ac? Does the snapdragon 800 vs 805 matter at all when downloading media via wifi?
