I understand about the older phones... I used a 4 for a week before the 6 plus came out and I almost went crazy...lol I would change to the next plan on ATT but I am afraid of having problems like you are facing with edge. Also, I want to be able to upgrade at the Apple Store as I have made that a yearly tradition and I know many of the people that I wait in line with from previous years.
Yea I turned my note 3 in and got the 6 the. Returned the 6 for the 6 plus.... Well Verizon screwed up and now they have to talk to the corporate office in new jersey to cancel my edge agreement so I won't be charged full retail for phones I don't even own. I'm clear of the 6 but still unsure of the note 3.
You shouldn't have those problems if u don't do what I did. Verizon was supposed to give me a temp phone on edge until I got my 6 plus but they messed up.
I feel a 6 plus 16 might be ok for me. I only keep a few songs on there and am always close to wifi. Limited games.
Try playing worms on a 4s with a friend. Lol it's a wash
