The list of devices Siri can voice control is getting longer thanks to the efforts of developers who are thinking outside of the iPhone 4S box. It all started when Applidium reverse engineered the Siri protocol and posted the files for anyone to use.

A developer named plamoni took the process a step further by creating an extensible Siri proxy server, which allows Siri to interact with other devices on a network without jailbreaking the iPhone. He successfully used his iPhone 4S to control a Wi-Fi enabled thermostat using the software.

Most of the hype surrounding the iPhone 5 display has been centered on its size, with industry observers predicting that Apple will increase the next generation display to 4 inches. New information points to an even more intriguing possibility, that the iPhone 5 will feature Sharp's IGZO display technology in a cutting-edge mobile touchscreen.

The diagram above from Semiconductor Portal illustrates the advantage of IGZO transistors. These indium, gallium, and zinc (IGZO) transistors replace standard amorphous silicon thin-film transistors in the Sharp components, which provide higher electron mobility. This means display pixels can be smaller and more light passes through the IGZO display.

The iPhone 4 has yet to officially launch in Brazil, but photos have already leaked of a locally-made 8 GB iPhone 4 hot off the assembly line. Foxconn has long been rumored to be starting production on the iPhone and iPad at a new factory in Brazil. Photos leaked on Brazilian site MacMagazine show an iPhone 4 with a unique model number and markings.

Also seen on the back of the iPhone is "Indústria Brasileira" instead of the typically seen "Assembled in China" tagline. Below this is the stamp of approval from the official Brazilian communications agency ANATEL. The version of iOS 5 installed on the iPhone describes the model number as "MD198BR" with the BR indicating Brazil.

Apple continually strives to improve the iPhone's picture taking capabilities, and the iPhone 4 and 4S are no different. Maybe the impressive low light capabilities and high resolution photos are not the look some photography buffs enjoy. If the five-element lens in the iPhone 4S is too perfect for your tastes Holga has just the accessory for you.

Now you can transform your iPhone 4 or 4S into a toy camera, Holga style. The SLFT-IP4 iPhone lens filter kit fits like a normal case on your device, but gives you access to nine different retro special effects without using software.

When it comes to smartphone photos taken and posted on popular sharing site Flickr, Apple just surpassed itself again. The iPhone 4S has flown up the ranks to beat the iPhone 3G as the second most popular device to snap photos with on Flickr. This kicks the iPhone 3GS down to third and the Android HTC EVO 4G into fourth place.

The reigning champion of mobile phone image uploads? The iPhone 4 retains its lead in the segment, blowing away the competition. In fact, when it comes to overall camera statistics on Flickr the iPhone 4 also comes in first place, ahead of several digital SLR models. The Canon EOS 5D Mark II and the Nikon D90 follow in second and third place respectively, with the Canon EOS Rebel T2i and Canon EOS 7D following behind.
