iPhone 4

Prior to the official unveiling of the iPhone 4 on June 7, 2010, two prototypes were brought to mainstream media, breaching Apple's normally secretive development process. Many of the speculations regarding technical specifications proved accurate.

The iPhone 4 is structured around a stainless steel frame which both acts as the primary structure for the device, and additionally acts as the iPhone 4's antennae. The stainless steel enclosure features three slits that divide the band into three sections; the left section of band acts as the Bluetooth, Wi-Fi, and GPS antenna, and the right and lower bands sections act as the antenna for GSM and UMTS connectivity. There is some debate as to whether or not this causes issues with signal strength and availability. The act of touching the gap between the two antennas with an un-gloved hand potentially bridges these two separate antennas, leading to poor signal reception.

Toyota 4Runner Performance

Toyota 4runner Performance 0-62 mph - The Toyota 4Runner is an SUV manufactured by Toyota and sold throughout the world from 1984 to the present. In Japan it was known as the Toyota Hilux Surf (豊田 ハイラックスサーフ Toyoda Hairakkususāfu). The original 4Runner was a compact SUV and little more than a Toyota pickup truck with a fiberglass shell over the bed, but the model has since undergone significant independent development into a cross between a mid-size and a full-size SUV. All 4Runners have been built at Toyota's Tahara plant in Tahara, Aichi, Japan or at Hino Motors' Hamura, Japan plant, and in Brazil. It's mid-size crossover SUV counterpart is the Highlander. Toyota will redesign the 4Runner for the 2010 model year.

All Toyota 4runners came with Toyota's Star Safety System which includes anti-lock brakes, electronic brakeforce distribution, brake assist, traction control and Vehicle Stability Control. Side torso airbags for the front rows as well as side curtain airbags for the front and rear rows were optional on 2005-2007 models and became standard on 2008 models.

The Hilux Surf version for the Japanese market was also available with a range of diesel engines, including a 2.4 L turbodiesel 2L-TE I4 up to 1993, followed by a 3.0 L turbodiesel 1KZ-TE I4. A small number were also made with a normally aspirated 2.8 L diesel 3L I4. A small number were also produced with a 2.0 L 3Y I4 naturally-aspirated gasoline engine. A common modification for normally aspirated diesel engines (e.g. 2.8L) is the retro-fiting of a turbo (with or without intercooler kit), which can significantly improve performance.
