I have been a long time T-Mobile customer and have been planning on getting an iPhone 6s Plus when it's released in October. Unfortunately, I lost my old LG G3 phone (paid in full) a while back and have been relegated to a Nokia Lumia 521 which suffers from poor battery life and cellular reception and seems to be on its last leg now. I've never been interested in leasing a phone before because I tend to keep my phone at least two years and then sell them privately. Considering all the problems I'm having with the Lumia 521 however, I was wondering what people thought of this Jump on Demand promotion for the iPhone 6. I've had to piece together what I've seen online as I can't locate the terms and conditions of this promotion. From what I gather, if I took this promotion, I would enter into an 18 month lease agreement and would pay $15 per month for 2 months to lease the iPhone 6 (I could turn in the Lumia to satisfy the device requirement). When the iPhone 6s Plus comes out, I could upgrade in October and at the end of the 18 months, I would have the option of paying the remainder of the 6s Plus retail price and would thus own the 6s Plus outright. Does that sound correct? Are there any hidden costs that I'm not seeing here? Since my original plan was to simply purchase the 6s Plus at full retail (paying monthly installments for 24 as opposed to 18 months) is there any real difference in the total cost of doing this after the 18 month period expires? Thanks!
