Samsung at the Mobile World Congress this week showed for the first time their Super active-matrix organic light-emitting diode display (Super AMOLED). The display is five times clearer and offers 20% visibility outdoors in the sun, but does it offer enough power savings for the iPhone 4G?, Apple did not use OLEDs in the iPhone 3G because of its heavy power consumption when browsing the web or checking emails, according to sources of OLED-Display.net. Apple has a longstanding arrangement with LG Display, but there is no OLED type of displays suitable for the iPhone 4G currently being manufactured by the company. Samsung is the only contender with a display capable enough to be used in an Apple product, when considering the large production and quality control involved. Just announced was the Samsung Halo phone using the Super AMOLED display in question, it’s a 3.7-inch WVGA (800×480) screen very suitable for an iPhone. In our interview with Rapid Repair on the iPhone 4g, Aaron Vronko Service Manager believes Apple would choose the next-generation of Samsung display technology, one of the deciding factors would be the increase in size and a 25% brighter screen.

Sling Media, makers of the SlingPlayer hardware and software packages will go live today with AT&T 3G capabilities for iPhone users. Previously only WiFi connected users could stream their videos over their iPhone, iPhone 3G and iPhone 3GS devices.
SlingPlayer allows users to stream their cable, satellite or DVR files directly to their outside devices over high speed internet, previously AT&T had disallowed 3G use of the system for fear that it would cause unnecessary congestion on their fledgling 3G service. AT&T announced several weeks ago that they would allow 3G service to be used with the iPhone SlingPlayer App, but Apple had to first approve the program, which is now available via the App Store. The cost of the 3G version is $29.99, with a free download available to users who have already purchased the WiFi version of the program.
In order to use the program users will also need to purchase a Sling Box which is hooked up to their home video setup and internet connection.

Sometimes, Apple's decisions about content in the App Store can be petty and anti-competitive -- like asking developers to remove any mention of Android. But sometimes, they make a call that seems to put users first. This time, it's a request that developers use your location to provide useful information, rather than just serving you location-based ads. Here's the text of the warning to developers, posted in Apple's developer forum:
If you build your application with features based on a user's location, make sure these features provide beneficial information. If your app uses location-based information primarily to enable mobile advertisers to deliver targeted ads based on a user's location, your app will be returned to you by the App Store Review Team for modification before it can be posted to the App Store.'
Developers might balk at the removal of a possible cheap and easy revenue stream, but I think Apple is doing the right thing, here. Apps like Foursquare and Gowalla, which allow business to advertise specials, should be unaffected, because they also your location for checking in, finding your friends, and other important game elements.

Skype users will soon be able to place calls from iPhones over the 3G network, thanks to an update to Apple's policies, according to a post on Skype's official blog.

Skype for iPhone currently allows Skype-to-Skype and Skype-to-phone calls only through a wireless connection. Until recently, Apple had banned VOIP programs like Skype from enabling calls over the 3G network. The new version of Apple's Software Development Kit, rolled out with the iPad, removes this restriction.

As a result, Skypers will be able to call each other for free from anywhere AT&T's network operates. No firm date has been set for the new feature, but the company promises that it will be available "real soon now".
