Apple App Store

Ever send a message with invisible ink to a friend? Now with the Black SMS app, text messages can be encrypted and decrypted easily by any iPhone owner with the right password. Once Black SMS is installed on your iPhone, the secret message is simply typed into the app and a password assigned.

Copy and paste the message into an SMS or email message, then send away. Just make sure you share the password with your recipient, because otherwise nobody will be able to read your message. Black SMS uses Advanced Encryption Standard for serious security, even though the app is simple to use and only costs $0.99 in the App Store.

Once again, Apple is offering one lucky winner a $10,000 iTunes gift card for simply downloading an iOS app. Of course timing will determine who wins, with the 25 billionth app marking the winner and another milestone in the 3.5 year history of the App Store.

Apple ran a similar contest when the App Store hit 10 billion downloads in January of last year. As of this writing there are less than 700 million apps remaining to be downloaded according to the Apple contest page.

Whether your iPhone is jailbroken or not, a decent SSH client can be useful to access other machines on the go. Jailbreakers can use an SSH app to browse and manipulate files directly on their Phones from the iOS command prompt. A popular app, Mobile Terminal serves this purpose but can't be installed directly from Cydia in iOS 4 or 5.

There is a workaround to install Mobile Terminal which is great because it's free. If you're looking for an easier alternative, Prompt comes to us from the App Store and can be installed on jailbroken or non-jailbroken iPhones.

If you're considering jailbreaking your iPhone for the first time, you should know there is an iPhone 4S jailbreak in the works, but it's not available to the general public yet, and it will be free. You should also know Apple is not a fan of jailbreaking, so it's never going to be available as an app in the iTunes App Store.

Apple recently pulled a $9.99 app by RiliSoft because it tricked people into believing it could jailbreak the iPhone 4S and iPad 2. The app cleverly named "Jailbreak" is actually a game, but Apple didn't like the way it tricked its users. You can see how the app's description mislead people from the screen shot taken by GottaBeMobile posted below.

The Google Books app has been missing from the iTunes App Store for about a week. 9to5Mac reached out to Apple and Google on Thursday, but no answer from either party has left them wondering why it disappeared. Google Books was just launched last year, and received an update this past April. Why do all that work to only pull the plug a few months later? Or did Apple kick them out?

9to5Mac points to Apple's new TOS that gives them 30% of all sales (they also mention Harry Potter, but what did he ever do to Apple?):
