Great news for parents who had to face insane credit card bills due to their kids making in-app purchases with their iPads and iPhones. The iOS 4.3 update brings password protection to in-app purchases, so you no longer have to worry about your kids being reckless with their purchases on your iPhone. Whenever you try to purchase something in-app, iOS 4.3 will require you to enter your iTunes account password. This move came after the FTC was asked to investigate apps that were allegedly trying to trick kids into making in-app purchases to gain benefits or advance further in a game. With in-app purchases not so easy to abuse now, games like Smurfs Village and the like should be seeing a lot less of purchasing starting this week onwards (provided parents update their OS to 4.3).
