Steve Jobs shakes hands with Eric Schmidt.

Apple co-founder and former CEO Steve Jobs threatened Palm CEO Edward Colligan with patent litigation if he did not agree to stop poaching Apple employees, according to a court filing that was made public on Tuesday.

Confidential emails between the pair, along with documents from Adobe and Google, have surfaced in a civil lawsuit that claims a number of major companies in Silicon Valley violated antitrust rules by entering into agreements not to recruit each other’s employees. Five employees are now fighting for class action status and damages for lost wages as a result of the “no-hire” agreements.

Google just announced its earnings for Q4 2012, and guess what? They made a ton of money. We’re shocked.

Actually, Q4 2012 was really great for Google. The company earned $14.4 billion in revenue, which is 36% better than what they did last year. While we tend to think of Google as an American company, only $5.99 billion of that revenue came from the U.S. while the rest was made in international markets.

Amazon has today announced that its in-app purchasing service, which is already available on the company’s Kindle Fire tablet and other Android devices, is coming to Mac, PC, and web games. This will allow developers to take advantage of Amazon’s service on those platforms to provide their customers with a new way to purchase additional content using their credit card or virtual Amazon currency.

While Amazon isn’t the first company to offer an in-app purchasing system, its service does come with some advantages that developers may not get from its rivals. One of those advantages is that their content will be available via Amazon.com.

Although Mozilla has stated that it won’t produce hardware for its upcoming Firefox OS, the company has teamed up with Spanish startup Geeksphone to offer a pair of developer devices. Called Keon and Peak, the devices are designed to provide developers with the opportunity to “tap the future of mobile” and get to grips with the platform that will soon be trying to steal marketshare from Android and iOS.

Google is said to be preparing a second-generation Nexus 10 tablet for Mobile World Congress in Barcelona next month. The device will reportedly offer a quad-core processor and faster graphics, making it a significant improvement over its predecessor — which was only launched last November.
