SIRI

Guess what are the top most popular smartphones in the U.S.? It's iPhone 4S, iPhone 4 and iPhone 3GS.

South Korean tech giant Samsung's the next big thing, the Galaxy Note smartphone or phablet (phone+tablet) with a massive 5.3-inch Super AMOLED screen, is now available for pre-orders from AT&T's official Web site. Who would be the toughest rival to reckon with after Samsung's Big Daddy debuts in the U.S.?

Nanosensor technology could allow for Siri to one day answer this question because NASA has built a cancer detecting mobile phone sensor at the Ames Research facility in California. Ames scientific researcher Jing Li is working on a small chip the size of a nickel that includes 32 of the amazing nanosensors. They are all made of different kinds of materials, and that lets them interact with different chemicals in unique ways.

First it was Smart TV, then 3D TV and now it's time for Apple iTV to complement living rooms. There's already widespread speculation about the company planning a cloud-based TV service, and the rumor received new legs when Walter Isaacson's posthumous Steve Jobs autobiography was released. In the book, Jobs discussed that television was the next domain Apple would conquer.

Both Apple and Samsung will be at the Mobile World Congress in late February, but it now looks like neither the iPhone 5 nor the Galaxy S3 will be debuting at the annual event.

Apple is expected to reveal the iPhone 5 at the Worldwide Developer's Conference (WWDC) 2012, which will take place in San Francisco from June 6 to June 10. The new phone is said to feature a bigger screen and 4G LTE.

Adding more fuel to the rumor around Apple's third-generation iPad, latest reports highly suggest that the tablet will arrive in two different versions towards the end of March. The device is also very likely to sport a faster quad-core A6 processor, making it the fastest iOS device ever.

Even though Apple doesn't like to reveal anything about its new releases before an official announcement, legions of fans want to know what they can look forward to when Apple upgrades the iPad 2 to the iPad 3 (or iPad 2S). That's because $500 is enough money to get people to think hard about buying the iPad 2 this close to an iPad 3 launch.

Apple's iPhone 4S has been extremely popular since its debut, so popular in fact, the Chinese debut in January 2012 nearly caused a riot when the six licensed Apple stores sold out of the devices. Still, it does cost $200, so if you're not quite ready to spend that much, you should consider the iPhone 4. The difference may not be enough for you to decide to spend the extra $100, but at least you can factor that in to your next smartphone purchase.

Apple's breakthrough achievement in the tech world is a result of its ground breaking platform in the form of iPhone and iPad which were launched in the past few years.

iPad 3, which is the next iteration of Apple's iPad 2, is expected to be launched anytime soon. Check out the top 5 anticipated features of iPad 3.

The next iPhone 5 has at various times been rumored to include LTE connectivity, larger display, a quad-core processor, new design and much more. However, what has been overlooked is that the important feature for the iPhone 5 may not be hardware-related.

This is the tablet battle of the year: The Apple iPad 3 versus the Asus Transformer TF700T HD. Although the new Transformer Prime HD won't be here until this summer, Asus released the Transformer Prime in December, and the Prime TF700T (HD) is nearly identical to it.

The rumors about iPad 3, or Apple's next generation tablet, has touched a fever-pitch with expectations growing that the tablet will launch in late February or early March. From a better camera and Retina Display to a quad-core processor and NFC technology, here's a rundown of the features Tech & Trend thinks iPad 3 will boast of (and not boast of).

Two solid AT&T phones have had their prices lowered now that the holidays are over, and the $150 Samsung Galaxy S2 or $100 HTC Vivid are good choices if your contract is up or you're looking to switch carriers. Both devices were $200 before the holidays, so if you were holding out for a better deal, here's your chance. Samsung released the Galaxy S2 about a year ago, so it's due for a replacement this year, but it's still tough to beat, even when compared to the iPhone.

Apple announced its most profitable quarter ever on Tuesday, but now that the bar is set so high, all eyes will be on the next iPad and iPhone to carry the company's success through the year.

Ever since the Chronic Dev Team released the GreenPois0n Absinthe untethered jailbreak for iPhone 4S and the iPad 2 running iOS 5 or 5.0.1, a number of Siri jailbreak tweaks have emerged, with more keep on rolling in.

Apple could ship a 42-inch TV set featuring organic light-emitting diode (OLED) displays as well as controls activated by the Siri “voice assistant” in the iPhone 4S, a report said.It could Apple TV or iTV.

It is now possible to install Siri on iPad 2.

An upgrade to the phone's operating system was then announced, amid hope it would fix the problem. Unfortunately, the upgraded iOS 5.0.1 failed to do so and the users were left further disheartened. They then stumbled upon an iPhone 4S jailbreak tweak that claimed to be able to fix the battery's handset problem.

Evi, a new voice-assisted personal assistant, developed and launched by True Knowledge, a UK-based Internet search technology company is expected to provide tough competition to Apple's Siri. Check out the video...
