I’m currently on the AT&T Next plan and ready to upgrade my iPhone 7. However I’m debating between two options - either getting the 8+ and keeping it for a year, or going with the X but keeping it for two years. The rationale behind this is to keep the monthly installment roughly the same no matter which way I️ go. Anyone have any suggestions? Either way I️ go, it’ll be a nice improvement over my current phone.
