Sending postcards to jail just got easier thanks to a new iPhone app called FlikShop. The app allows users to easily create and send personalized postcards to prison inmates in three easy steps.

The app is very simple to use: Select a photo from your iPhone's library, write a personalized message, fill in the prisoner's name, inmate number and select the state and institution you would like the postcard to be mailed to. After a $.99 charge, FlikShop will deliver a glossy, 600dpi postcard with a removable and personalized note to your favorite inmate. Don't have an iPhone? No problem! Just visit Flikshop.com to send a postcard directly from your computer.

Prepaid iPhones have arrived at Virgin Mobile, giving those who prefer a contract-free smartphone a new option. Virgin joins Cricket Wireless in offering the iPhone 4 and iPhone 4S unsubsidized with month-to-month billing.

Pricing is set at $650 for the 16 GB iPhone 4S, and $550 for the 8 GB iPhone 4, matching Apple's currently listed unlocked iPhone prices. Although this may cost more than Verizon's or AT&T's subsidized devices with a two-year contract, customers can save on data plans with Virgin Mobile.

If James Bond had an iPhone, he'd be using Wickr. Secret messaging between iOS devices has been around for some time, with apps such as Black SMS which encrypt messages to keep them private. Now a free app known as Wickr has taken the concept to a new level.

Not only does Wickr encrypt messages in transit, keeping them away from prying eyes, but the app actually is capable of sending self-destructing messages with a limited lifespan. After these messages are received, they are securely erased from the recipient's iOS device based on the sender's instructions.

Jailbreak developer Ryan Petrich has released a new tweak called BrowserChooser in response to Google's popular iOS Chrome browser app being released yesterday. Petrich tweeted: “BrowserChooser is up on rpetri.ch/repo. Loving Chrome for iOS so much that it had to be built.”

The tweak allows you to change your default browser to Google Chrome, Opera Mini, iCab Mobile, Dolphin Browser, Atomic Browser or Safari. You can toggle between all your available browsers in the Settings menu. Petrich's tweak arrived around the same time Chrome became the most downloaded free app in the App Store.

A new web browsing option for iPhone and iPad users is now available thanks to Google. The Chrome web browser requires iOS 4.3 or later and provides a bevy of features to enhance web browsing on iOS mobile devices. One of the key highlights is the ability to sync your browsing between these devices and your desktop computer.

All of your omnibox data, tabs, bookmarks and passwords are synced when logged into your Google Chrome account. You can even send pages to your iOS device from a computer to read later offline. Much like the desktop version, Chrome for iOS also has a private browsing mode.
