Tuesday, Skype released an official iPad app - and then pulled it. 

"Skype for iPad" app rolled out to the iOS App Store early Tuesday, starting from New Zealand, the app's debut swept across worldwide storefronts. 

But soon after, the app disappeared.

Around midnight Wednesday, the company explained on its Twitter feed,

"To ensure your best Skype experience, we've temporarily removed Skype for iPad which went live prematurely today."

"We know you've been eagerly awaiting Skype for iPad and apologize for the inconvenience," added Skype.

It is unclear why the app was pulled, and when it will be back up.

"Skype for iPad" rolled out as a free app, that allows users to make video calls over 3G and Wi-Fi mobile networks. With some fee, phone calls to landlines or mobiles as well as an Online Number from Skype are available.

The new app makes the most use of the big screen of iPad.

Apple earlier noted that Skype's iPad app would enjoy "similar success" as the iPhone version, providing the same functionality.

The iPhone version of Skype either offered a small interface in the middle of the screen or the full screen view with a low quality image.

The app is compatible with iPhone, iPod touch, Mac, and PC users, but video calling requires iOS 4.0 or above. Two-way video calling is enabled for 2nd-generation iPad users as well as iPhone 4 and 4th-generation iPod touch  users, while first-generation iPad and 3rd-generation iPod touch users can only receive video as expected.

According to the lucky ones who downloaded the new - and at the moment inevitably exclusive - app, their experience with Skype on the iPad has been great. Whether Skype will visibly improve some features or not, the app's disappearance has drawn users' higher attention for its reappearance.
