Mine says 2/25/12 and I got my iPhone 4 on launch day (6/24/10). My line typically gets the 20 months. Man, I would love to get a once a year upgrade! If AT&T can do that for me and for any phone (not just iPhone), I would stay with them for many more years!
Last night, I was doing a roadmap of future gadgets I plan to get within the next 5 years after studying NVIDIA's Tegra roadmap of Kal-El, Logan, Wayne, and Starks. I came down to WP7 vs QNX for my next phone. But I don't see RIM pushing QNX that soon and it probably needs a few years of refinement. Android still lacks polish, and since they are allied with NVIDIA, it seems like I can just wait for Starks by 2014-2015. NVIDIA has a roadmap that seems to make specs obsolete before they arrive. But I pray a SE "PlayStation Certified" gets Starks by 2015. The NGP/PSP2 stays home alot more by then.
So likely WP7 by Feb-Apr 2012, and then QNX by Oct-Dec 2013. Then a PlayStation Android phone by Jun-Aug 2015. The sooner I can upgrade, the better. I don't see Starks (Tegra 6) out until that year even if it says 2014. By then, the XPERIA PLAY phones would be in its 4th or 5th gen which makes it more refined and mature. Heck, it took 5 years until Microsoft got it right with the sleek Xbox 360 S last year.
I really hope my date gets moved up in some way. We pay over $130+ per month for a family plan. I would love to get a cheap Samsung Focus this summer! I will never sell my iPhone 4, but I can understand the resellers doing it because you can make such a nice profit on something we enjoy having anyway! For me, it is all about creating a superteam of phones (iOS, Android, WP7, & QNX). I don't even like Sammy or Microsoft, but I have been eyeing that Focus for weeks now! I like the price, screen, OS, and design. Just hate the power button being on the side. After three years with iOS and realizing I am no longer an app whore, I just wanna try new things.
