Another update to the Skype iPhone and iPad apps has been released, adding new features and bug fixes. Desktop users will recognize some of these features, which include the ability to log in with your Microsoft account. This integration is the next step in Microsoft's plan to replace the Messenger IM client with Skype.

The Skype iPhone app can now be used to chat directly with contacts on Hotmail, Messenger or Outlook.com. Those who are new to Skype will find that an account can be created directly from the app, no computer required. Account holders with the iPhone 5 probably noticed that Skype optimized its app for the larger display, already released in a previous update.

Chances are you send a lot of messages from your iPhone. Now if your device is jailbroken you can speed up the process with a tweak named ImmediateSend. Why bother going to the Messages app every time you want to reply to an SMS or iMessage?

That's the theory behind ImmediateSend, which will deliver a pop-up box with simple options when you're interested in sending quickly. If the recipient of the message can handle an iMessage, that will be presented as an option, along with buttons for reply with SMS and go to the full blown Messages app. Just enter the text you want to reply with and tap the button of your choice.

When it comes to iPhone jailbreak tweaks, there have been many attempts to improve or replace the stock multitasking app switcher. Some find the multitasking dock painful to use, including having to scroll all the way to the left to find a volume control. Now for those with jailbroken devices there's a tweak called jLauncher that makes multitasking better.

Once installed, jLauncher can be invoked with any Activator gesture. This also means you must have the Activator package installed on your device. Double pressing the home button is how the stock multitasking app switcher pops up on an unmodified iPhone. Assigning this gesture to jLauncher will effectively replace the old dock.

Incredible photographs from around the world are only an app away. 500px has officially launched an iPhone version of their highly acclaimed iPad app. Of course, the free portal to content from the 500px website has been optimized to take advantage of the larger iPhone 5 display.

500px version 2.0 features an all-new, designed from the ground up user experience made just for the iPhone. This includes the Flow timeline feature optimized specifically for mobile devices. Although this current version does not provide for photo uploads from the iPhone, the feature is in the works for future release.

The iPhone 5 release has pushed Apple over the top. Regaining its lead for the first time since March, Apple's iOS smartphone sales are once again dominating the US market. According to Kantar World Panel, Apple is on track to surpass the previous high of 49.3% of smartphone sales seen after the iPhone 4S launch.

Second place Google Android is not far behind at the moment, but the devices have seen a sharp decline in sales with the iPhone 5 launch. Google's share of US smartphone sales had surpassed 65% just one year ago. While Windows and other smartphones linger at the bottom, BlackBerry maker RIM has seen a steady decline in US sales over the past two years.
