Hello, long time lurker first time poster. The iPhone 5 will be my first smartphone. I'm really excited about getting one, but in reading some of the post on here people talk about the need to upgrade because their 3GS has died or even that their IP4 is on its last leg. I am not someone who upgrades every year. Heck I am still rocking a Sony Ericsson w600i which I know is older than many of the iPhone models and its still going strong. I tend to take good care of my electronics, but I need to know what is the general consensus regarding iPhone durability as it will be my phone for at least two or three years. Thank you for your replies in advance.
