Is the iPhone 5 worth the upgrade, the answer is yes and no. If you 
want a faster phone, 4g, a larger screen in a lighter and thinner form factor then go for it. But if you want to make use of NFC technology and connect it to your tv , then don’t go for the upgrade. Even the 4g option is not available for certain networks around the world, due to the phone not being able to receive all the 4g frequencies around the world. People who want these extra features will have to wait until next September or October for the iPhone 5S to come out. It worth pointing out that Apple is bringing out a special hdmi adapter that will bring tv out functionality to the phone in a couple of months. Its also possible once there is a jailbreak option for the phone, there will be a jailbreak solution that will enable you to use an existing 30 pin hdmi adapter with the new lightning port adapter.
Some commentators have said the new iPhone 5 is just a longer version of the iPhone 4S, but it’s obviously much more than that. If people choose to upgrade it will be a simply a subjective choice based on what they want to do with the phone, if a person wants to make use of NFC technology and use the phone with a sd card and for internet browsing then go for the Samsung Galaxy s3, due to the extra real estate on the screen and the other extra features it has.
