Assuming you don't purchase an unsubsindized phone each year and you're under a 2 yr. contract. Would you prefer your contract to expire with the introduction of each new model with major improvements or the S model with minor improvements? My Verizon contract expires in April 2013 which will give me the option to upgrade in Dec. 2012, actually 20 months. So if I upgrade to iPhone 5 in Dec. 2012 that would put eligable to upgrade again in September of 2014, actually 20 months. This would put me in the 2 yr. rotation cycle of each New phone reveal. If I don't upgrade in Dec. 2012 and wait for iPhone 5s, probably Sept. 2013, I would then follow the 2 yr. S model rotation. Your thoughts, thanks.
