Just not feeling the new phone at all. I prefer the size of my 5s and cannot believe I am returning it. I have had every single iPhone made and cannot get used to the size of the 6 as I always use my phone with one hand. Anyways, do I need to make a reservation or can I just walk in and return the phone? Also, does anyone know if ATT will charge me for the 10 days of usage? Thanks guys!
