Black 128gb iPhone 6 or 6 Plus, need to go in store to check size compatibility. Currently have iPhone 4, ATT, and will stay with ATT (transmit voice and data at same time).
My current plan is $132 month, unlimited voice $70, unlimited texts $20 (been using about 3,000 texts a month), and the grandfathered "real" unlimited data $30 (been using 7gb/month for the last 7-8 months, oddly I don't stream video and stream very little music, don't use GPS because my GPS is broken along with the wi-fi, I've smashed the phone a few times). I usually have location services turned off because of weak battery concerns, and the GPS doesn't work. I don't have tethering on my plan because that would require losing the unlimited data. Not worth it to tether laptop. One day I'll try looking at bill to see where the data usage is coming from. I'm sure if I have wi-fi, that my data usage will go down. I've never concerned myself with data usage since 2007 (7 years). I looked at a couple bills from over a year ago and data was 2-3gb when wi-fi worked, of course I also used GPS then too. 2 years ago I used well under 1gb. Stuff changes.
I hope I can get serious $$ for my old iPhone 4 with ATT or somebody. Can always change my plan later, but concerned about data charges.
