The world's first smartphone for blind people is here. Soon, they will be able to read SMSes and emails on this phone, which converts all text into Braille patterns.

"We have created the world's first Braille smartphone," says its innovator, Sumit Dagar, whose company is being incubated at the Centre for Innovation Incubation and Entrepreneurship, located in IIM Ahmedabad campus.

Security flaw affecting 120,000 free Android apps revealed

By Tech Gig
A flaw in commonly used applications on Android smartphones such as texting, messaging or microblogging could spread private information or allow forged fraudulent messages to be posted, a recent study has revealed.

The flaws start to appear just when the victim downloads a piece of malicious code onto their phone which could be hidden in a useful app, or attached to a 'phishing' e-mail or web link, that could harm the vulnerable programmes by invading them.

Xu has found that it is possible for an attacker to access and read personal information, including even 'private' messages from one of the popular text-messaging app, Handcent SMS that allows users to place som…
