Apple iPhone 3GS Unlocked Phones

A Quick Shopping Guide to the iPhone 3GS Unlocked Smartphone

The iPhone 3GS unlocked smartphone is like having a personal computer in the palm of your hand. You can use the device to place calls, take pictures, browse the internet, and connect with other people. Released in June of 2009, this low-cost smartphone represents the third generation of Apples iPhone series.

Why should you buy an unlocked smartphone?

The advantage of an unlocked smartphone is that it isnt tethered to a specific cellular carrier. If you purchase a phone thats unlocked straight out of the factory, then you can choose any carrier you want, assuming its on the right network. This could be advantageous if you frequently switch between carriers or you travel abroad and need to use an international SIM card. Any software tied to a specific cellular carrier will be absent as well.

What should you look for when choosing a used smartphone?

One of the most important factors you will want to consider is the status of the rechargeable lithium-ion battery. Since the battery only has a limited number of charges, you will probably want one that is in good working condition. Apart from battery life, you should also look out for any signs of wear on the smartphones exterior. If the smartphone has low battery life or a scratched screen but is otherwise in good working order, then it is possible to replace the parts yourself.
