Long-time Sony Ericsson users may find the Hazel the perfect cure for nostalgia. Monster gadgets like the Vivaz and the XPERIA X10 are trusted to get the brand back on track. But for all we know, it takes a good old-fashioned slider to rekindle the romance.The Hazel falls in the company’s GreenHeart line of phones. The echo-friendly vibe is perhaps supposed to make up for the missing Cybershot and Walkman magic. The green credentials are all there anyway. The phone is made of recycled plastics and uses waterborne paint. There’s a power-efficient charger in the tiny, shipping-optimized retail box and no user guide (it’s on the phone’s memory instead of being printed on paper).GreenHeart is Sony Ericsson’s way of saying they care. We all do – but a phone is as likely to save the planet as it is to give you a direct line to Elvis. Either way, it’s not the phone’s fault. So, the Sony Ericsson Hazel will be considered for what it is and what it does. Not for the color of its heart.The Sony Ericsson Hazel isn’t just another feature phone. It can’t afford it on a market like today’s where cheap smartphones and touchscreen lurk behind every corner. GreenHeart implies some sacrifices but users won’t have to give up on phone features. The Hazel is a high-performance handset with an ample 2.6” mineral glass covered scratch-resistant display solid imaging and all sorts of connectivity options. Not to mention it’s totally weather-proof.In terms of connectivity, the Hazel sure is a handful. Along with the HSDPA/HSUPA support (for data transfer speeds reaching 7.2 Mbps), the slider also boasts Wi-Fi and Bluetooth, and a built-in GPS receiver to top it off.The Sony Ericsson Hazel knows social networking is essential these days and it gives it all – right on the homescreen. The nifty widget set gives you on-screen live updates from Facebook, Twitter and MySpace.Of course, the Sony Ericsson Hazel has its flaws as well, and we’re not going to let them by. But before we dig in deeper, let’s first take a look at the retail package and check the phone’s build and feel. Jump to the next page for a chance to see the Hazel from some new angles.
