An overseas friend uses the Viber app on her iPhone for free VOIP international voice calls and text messages on her smartphone. I installed the free app on my Android phone and tested it. Setup was swift and quality was superb.
I was at the petrol station and the attendant was filling up an almost empty tank with petrol. While waiting, I whipped out my Android phone, searched the Android Market for Viber and installed it. Before the attendant had finished filling up the tank, I was already chatting with my friend in Kuala Lumpur on her iPhone – for free.
Set up was really simple on the Android phone. Once it was downloaded and installed, it gets your permission to access your contacts and sends you a 4-digit access code to activate your account. After that, you’re set to go!
Viber is free and works on the iPhone and Android phones.
The interface looks similar to the usual numeric dialpad with tabs to access recent calls, contacts, messages and more activities such as inviting friends, sharing on Facebook, tweeting etc.
Basically, Viber emulates the usual phone calling and sms usage – everything is based on your regualr phone number.

Your account id is your phone number. If the party you’re calling has Viber installed on her Android or iPhone, you just dial her usual number, complete with international dialing code, to get connected. Viber is currently only available on the iPhone and Android phones. A BlackBerry version is in the pipeline.
Quality was good. Voice quality was loud and clear, although there was just a split-second lag, which didn’t affect the flow of the conversation in the slightest bit.
If the other party does not have Viber installed yet, the app gives you the option to place a regular call through your carrier.
At the Worldwide Developers Conference (WWDC) 2011 today, Scott Forstall – Apple’s senior vice president of iOS – paraded 10 of the promised 200 new features for the iPhone, iPad, and iPod Touch.

Notification Center provides iOS 5 users with an innovative way to easily access all notifications―text messages, missed calls, calendar alerts, app alerts and more, all in one place, from anywhere in iOS 5. When they arrive, notifications appear briefly at the top of the screen without interrupting what you’re doing. With one swipe you can see all your notifications, and a simple tap will take you right to its app for more detail.

Newsstand is an easy-to-organise bookshelf displaying the covers of all your newspaper and magazine subscriptions in one place. A new section of the App Store features just subscription titles, and allows users to quickly find the most popular newspapers and magazines in the world. For subscribed titles, new issues appear in the Newsstand and are updated automatically in the background so you always have the latest issue and the most recent cover art.
Safari sees new features for the browser in iOS 5. Safari Reader will strip down poorly formatted pages into an RSS-like view, and provides a link that allows you to e-mail the entire text of a story from within Safari. Reading List lets you save articles to read later and they automatically show up on all your iOS devices. Tabbed browsing is now available on the iPad making it easy to flip between multiple web pages on the tablet.
iOS 5 includes built-in Twitter integration, so you can sign in once and then tweet directly from all your Twitter-enabled apps, including Photos, Camera, Safari, YouTube and Maps with a single tap. New APIs give third party developers the ability to take advantage of the single sign-on capability for their own iOS 5 apps.
iMessage in iOS 5 brings the functionality of iPhone messaging to all of your iOS devices―iPhone, iPad and iPod touch. Built right into the Messages app, iMessage allows you to easily send text messages, photos, videos or contact information to a person or a group on other iOS 5 devices over Wi-Fi or 3G. iMessages are automatically pushed to all your iOS 5 devices, making it easy to maintain one conversation across your iPhone, iPad and iPod touch. iMessage also features delivery and read receipts, typing indication and secure end-to-end encryption.
With the new PC Free feature, iOS 5 users can activate and set up their iOS device right out of the box with no computer required, and iOS software updates are delivered over the air and installed with just a tap. Wi-Fi Sync in iOS 5 transfers and backs up your content securely over SSL and wirelessly syncs purchased content from your device to your iTunes library.

“Today it is a real hassle and very frustrating to keep all your information and content up-to-date across all your devices,” said Steve Jobs, Apple’s CEO. “iCloud keeps your important information and content up to date across all your devices. All of this happens automatically and wirelessly, and because it’s integrated into our apps you don’t even need to think about it—it all just works.”
• The App Store and iBookstore can now download purchased iOS apps and books to all a user’s devices, not just to the device they were purchased on. Simply tapping the iCloud icon will download any apps and books to any iOS device (up to 10 devices) at no additional cost. The App Store and iBookstore now let a user see his/her purchase history.
• iCloud Storage seamlessly stores all documents created using iCloud Storage APIs, and automatically pushes them to all of a user’s devices. When document is altered on any device, iCloud automatically pushes the changes to all the other devices. Apple’s Pages, Numbers and Keynote apps are already using iCloud Storage. Users get up to 5GB of free storage for their mail, documents and backup — and this does not include the storage for music, apps and books purchased from Apple, as well as the storage required by Photo Stream. Users will be able to buy even more storage, with details announced when iCloud ships this fall.
