Ok so I have the iphone 5 and I really do like it a lot, but there are some things I like about the nexus 4 as well. I have had 3 android devices before I got the iphone 5. I am thinking about buying a nexus 4 and switching sims out so I can use both. I am on AT&T so there would be no problem with networks. Has anyone done this? If you have tried this are there things that are just not practical about it? Also I know I need a sim tray, but does anyone have a suggested for which one I should get?
