When the invisibleSHIELD was launched in 2007 we featured an in-depth review of the invisibleSHIELD for the iPhone and found it to be the best product of its kind. As a long term user of the product myself, I can say the invisibleSHIELD continues to deliver on all of its promises.

Developers have found new header files in a directory labeled "compass" under iPhone OS 3.0 beta 5. These files point to Japanese company Asahi Kasei’s azimuth sensor No. AK8973. The reference describes a chip otherwise known as a digital compass, or a magnetometer, that comes bundled with a master clock oscillator.

First quarter mobile phone sales may be off almost nine percent from last year, however the smartphone market continues to heat up. Gartner reports that Apple has doubled its market share from last year, with sales of 3.9 million iPhones in Q1 2009, representing 10.8 percent of global smartphone sales.

Nokia still leads the pack with 41.2 percent, although this is a decrease from last year's 45.1 percent market share.

Tap on either side of the screen or flick to turn pages.

Apple has posted two job opportunities that could give further insight into the hardware and advanced capabilities coming our way on the next generation iPhone. Video recording and an improved 3.2 megapixel camera have been confirmed.

It seems Apple is ready to develop some exciting ways to take advantage of the new hardware. The following is an excerpt from a job description from Apple:
