Today we're answering some of the most frequently asked questions about iPhones. So, from getting an iPhone 4 cheap on contract to which model is best for you, we've got all the answers right here, all you have to do is read on...

What's the Big Deal with iPhones?

iPhones are the bestselling mobile device on the market, and thousands of them are sold every day. A certain percentage of people are simply buying because Apple has a great marketing team and the phones are seen as cool. However, there are some great features on iPhones. You get a phone that's not just good looking, but that has great specs, is fast and is easy to use. And iPhones have great compatibility, meaning that there are lots of downloadable games and programmes for them. Probably the biggest selling point of an iPhone is that it's so intuitive. The user experience is great, and the device is so easy to use that a child could use it without a problem.

How Many Models are On the Market?

Apple doesn't automatically retire older model iPhone when a new model comes out, so there are a few models on the market. The newest model is the iPhone 5, but you can still buy both the iPhone 4S and the iPhone 4. Some places also still sell some of the older iPhone 3 models, but these are hard to find nowadays.

Which Model Should I Buy?

As the newest model, the iPhone 5 is top of the line, and it does have a larger screen and a faster processor than any of the other models. However, except for the screen and processor, the iPhone 4S is identical to the iPhone 5 and is much cheaper. You get the same software, most of the same features, and the same camera on the iPhone 4S for around a hundred pounds less. The iPhone 4 is the oldest model generally available, but it's still a great mid-market phone. You might not get all the bells and whistles of an iPhone 5 or 4S, but you still get a phone that's fast enough to run all the latest software and has a great screen. Which phone you go for is probably down to how much money you have to spend, but all three devices will give you a great phone experience. Older iPhone 3 models will probably be too slow to run the latest software and games, so are best avoided.

Where Should I Buy?

iPhones are available in plenty of places. You can buy direct from Apple, using their web site or an Apple store. You can get iPhones with all mobile service operators, though their prices tend to be a little higher. iPhones are available from many high street retailers as well. You have a lot of options, and will need to do a little comparison shopping to see who's going to give you the best price on the model that you're looking for. You can also shop online. Online shoppers often get discounts from retailers, so it's definitely worth checking online before you buy.

Should I Get the iPhone 4 Cheap on Contract?

There are a few mobile operators offering the iPhone 4 cheap on contract these days. And this isn't necessarily a bad idea. Whilst incentive contracts don't always make good financial sense, given that a lot of the time you end up paying far more than the retail cost of your phone over the course of your contract, with an iPhone 4 you generally get a pretty good deal. Contracts with Vodafone and Orange in particular are great deals, with no money down, meaning that you can pay nothing and walk out of the store with a new iPhone 4 in hand. If you're in a position to sign a new contract and you want the iPhone 4, then this is probably the best way to get one.

How Reliable are iPhones?

Generally, iPhones have great reliability, and they seldom break. There are occasionally faults with new models, but Apple are quick to fix these faults and offer refunds. Plus, all Apple devices come with two year warranties, so should something go wrong then you can return the phone. The main weak point on the iPhone, like on most touch screen smart phones, is the screen itself. The screen on the iPhone is quite easily broken should you drop the device. You also can't change the battery yourself on the iPhone. Should you need a new battery, you'll have to take your device to the Apple store and have a technician fit a new one. Finally, iPhones are quite susceptible to water damage. These phones do have a special sticker inside the casing that will show a technician if the phone has been exposed to water, and this will invalidate your warranty, so you'll want to be careful.

Are There Down Sides to Owning an iPhone?

Probably the thing that most people complain about with the iPhone is the inability to personalise it. Apple are quite strict about how their software is used, and unlike an Android phone, it's tough to change the wallpaper or get different kinds of icons on your screen. For the average user this probably isn't going to be a problem though. Apple are also quite strict about which apps are available through the App Store, and since you can only download apps with the App Store Apple will be controlling your choice of downloadable programmes.

Any Extras I Should Think About?

Yes. Buy a screen protector, the screen is delicate and breaks easily. Buy a case to protect the casing of the phone. Finally, get yourself some insurance. An iPhone is expensive and should it get lost, stolen or broken, you're going to have lost a lot of money. Insurance, either through Apple or through your mobile operator will protect you from this loss.
