The iPhone 3GS was just unveiled by Apple last week at WWDC in San Francisco, and while it did not set the world alight like the original iPhone did a couple of years ago, we’re pretty sure that it is going to do pretty well on the sales front simply because it is an iPhone and bears the famous Apple trademark, being simple and intuitive to use in addition to its versatility compared to other more business-oriented smartphones. Well, one of the major drawbacks would be having to consign oneself to a 2-year contract if you want to get the iPhone 3GS for a cheap price, otherwise an unlocked unit will burn quite a big hole in your pocket. There is a method to circumvent this, however, with a new SIM card that will make unlocking the latest iPhone 3GS handsets a snap in a much simpler process than ever before. Known as the 3Gs 3.0 Unlock Sim for the Apple iPhone, this product is as dummy-proof as it can get, being one of the simplest and most reliable solutions to date that plagues iPhones locked to AT&T as a network provider. Just like a magical master key, the 3Gs 3.0 Unlock Sim is able to slot straight up on any existing SIM card in your iPhone 3GS, where it will function as some sort of ‘key’ to unlock iPhone 3Gs 3.0, hence making it compatible with virtually any other SIM card that has been inserted. According to company director Mark Scott, “Our Unlock Solution will add the Cydia and Installer Application to your iPhone. This will allow you to add thousands of free applications to your iPhone, like games, utilities, tools, NES emulators, custom springboards and the list goes on. Cydia and Installer are similar to the iPhone Appstore, except all the applications are completely free.”
