The popular photo sharing site Flickr first launched its native iPhone app in September 2009. The latest update, version 1.2, is now available on iTunes and takes advantage of new features in the iOS 4 operating system. Multitasking allows photo and video uploads in the background instead of preoccupying the iPhone until the task is complete. A badge on the app icon indicates how many uploads are processing.

Fast app switching means that every time you open Flickr, the app will remember exactly where you left off last time the app was used, and you can continue what you were doing. HD video upload capability will be useful for those iPhone 4 owners who enjoy recording 720p video on their devices. Hopefully Flickr will add high-resolution support for the Apple retina display in the next update.

In the wake of what Steve Jobs referred to as "Antennagate," Apple has launched an informational website to follow up on its Friday press conference on the iPhone 4. Much of the smartphone graphics and testing facility photos presented at the event are explained in detail on the new Apple pages. Pictured below is one of Apple's 17 anechoic chambers, which accurately measure antenna and wireless performance.

Apple highlights the fact they have spent thousands of hours logging tests in special facilities like these and in the field with prototypes of the iPhone 4 and all of their wireless devices. These state-of-the-art facilities cost Apple over $100 million to design and build.

Apple, recently under fire for iPhone 4 antenna problems, publicly addressed the issue in a special press conference at its Cupertino headquarters today. Steve Jobs explained that the company isn't perfect, but they want to make their users happy. Over three million iPhone 4 units have already been sold.

According to Jobs, for 22 days Apple has been working non-stop on determining the root cause of the problem and coming up with a real solution. Reports have indicated that connecting a gap with your hand in the metal band around the outside of the iPhone 4 can cause a drop in signal strength. The media has affectionately referred to this hand position as the "death grip."

Apple has released the first iPhone firmware update since iOS 4 was launched not even a month ago. The operating system officially went public on June 21 and has shipped on millions of iPhone 4 devices since then. iOS 4.0.1 is a minor update with changes to the cellular signal bars.

Apple promised the update after the company discovered an error in the way that signal bars were representing signal strength in areas with poor reception. Apparently the iPhone was making the signal appear stronger than it actually was at the lower end of the scale.

Dev-Team member planetbeing has demonstrated the first unlocked US-purchased iPhone 4 in the world. With a custom-cut Rogers SIM card and some coding magic, his iPhone dialed Rogers customer service and displayed the Rogers carrier logo on the home screen.

MuscleNerd and planetbeing are working simultaneously on two different unlock solutions, and plan to release the best one when the time is right. Apparently the software needs work even though the end result is functional. Dev-Team may wait until Apple releases iOS 4.1 before making the iPhone 4 unlock public.
