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.

Apple and Android users who download the new Mitt's VP app will be the first to know who the Republican nominee chooses as his running mate for the 2012 election . Beth Myers, senior advisor to Romney made the announcement on Tuesday:

Romney supporters can download the free iOS app from the App Store, and sign in using their MyMitt or Facebook accounts to receive a notification when the announcement is made.

Samsung has partnered with software maker Media Mushroom Applications to help iPhone users make the switch to the Samsung Galaxy S III. The two have created an app that allows users to easily transfer their iTunes and iOS data to Samsung's Galaxy line-up.

The Easy Phone Sync app uses an USB connection to transfer music, contacts, messages, photos and videos from your iTunes backup on your computer, to any Samsung Galaxy device. It comes in two parts: An app that runs on your Samsung smartphone and a Mac/PC client. I'm not sure if droves of iOS users are rushing out to buy a Galaxy S III, but it's a smart marketing ploy by Samsung.
