If you are looking into getting your iPhone fixed then you might also be considering getting it upgraded instead. Knowing whether or not to fix problems or replace them with a new phone will come down partly then to whether or not you think the updates are worth the extra expense (they are often quite superficial).

At the same time though, knowing the difference between different iPhones can help you to choose iPhone 2g or 3g repair respectively, and to identify what type of iPhone you have. It will also help you with choosing your new device.

If you have an 2g and decide that the differences are tempting enough that you want to upgrade it when it breaks, then you should still get it repaired so that you can trade it in and get a significant discount on your new iPhone 3g.

Following are the differences between iPhones:

The first generation of iPhone was significantly limited compared to the current generations of devices. The main and most damning problem with the first wave of iPhones was the fact that they did not have 2 or 3g. This gave them a much slower connection and meant that the connection was available in far fewer places. Streaming YouTube videos is not quite the same joy, and neither are many of the other advantages.

If you have an iPhone 2g then it will be significantly quicker than the first generation, but still not as good as the 3g devices. It also lacks many other features in the newer models. It does however feature an updated camera over the first wave.

The 3g iPhone is a step up from its two predecessors and is significantly faster. At the same time it also has a much higher megapixel camera.

The iPhone 3gs is just slightly faster than the iPhone 3g again and also boasts a slightly higher mega pixel camera. On top of this it also has a compass which allows for the use of augmented reality apps such as Layar and more effective geotagging and navigation.

The iPhone 4 is a step up in many ways and features the highest speed connection yet along with the highest mega pixel camera. It also has a faster OS and a much higher resolution and is one of the most powerful phones on the market. However as well as these boons it also features a niggling gripe – that being that it can’t receive any signal when held for texting.

There are other differences between iPhones too, and specifically this relates to the amount of memory they can store. Unlike most phones, they have no expandable memory meaning you’re stuck with what you have got which will normally be an 8 or 16 gigabyte hard drive.
