iPhone 6 to ?? So, my 3 year old 6 is on its last legs (awful battery, getting slower by the week, crashing etc.) so I think it is high time I went for a newer model. I had this dilemma when upgrading from the iPad to to air1 or air2, and eventually went for the latter. I am cost conscious so 7 is appealing but I do worry about older phones being supported for a lesser amount of time, however unsure I can justify the extra cost. I also hate the idea of a 24 month contract now that I am on a £23/month sim only. Be good to get advice from those in/have been in a similar situation.
