My First lasted 4 years. [2G, VGA Camera] 2nd Phone lasted 5 years. [3G, GPS, WiFi, Bluetooth, Radio, 5MP Camera] 3rd Phone 2 Years and counting. [4G, GPS, WiFi, Bluetooth, Camera + Front Camera] It's a simple pattern. Every new phone buy should be a major Technology Upgrade, not just specification upgrade. So Minimum Requirement for my next phone will be [5G]. Hopefully within next 2 years. :)
