Going to make the jump to iPhone with my next cell purchase. I'm tired of these garbage handset manufacturers never releasing Android updates. They flood the market with their Android clones. Then they abandon users and their products, apparently too much work to offer updates to their customers. I'm still stuck on Android 2.1 with my Samsung phone. I hate them. Scenario: I want to purchase the next iPhone, off contract, and go with T-Mobile's no-contract plan which has unlimited talk + text. I am interested in the HD voice you can get with iPhone and T-Mobile. WiFi calling would be great if I can do it with the next iPhone. Questions: 1. When will the next iPhone for T-Mobile be released? 2. Where can I, or should I, purchase a no-contract phone for a good price, works with T-Mobile, and has HD voice? I don't want some black market phone stolen off the subway, just a good place to purchase where I'm not getting ripped off. 3. Will the T-Mobile no-contract plan allow me to use the HD voice feature? 4. Will the next iPhone for T-Mobile permit wifi calling? Thank you for any advice or guidance you can provide.
