I've had a lot of phones over the years. Nokia, LG, Samsung, HTC.. I always thought the phone I had was great and was a real fan of HTC, determined to get a new HTC once my contract was up. However, then I got the iPod Touch and completely fell in love with the iOS (operating system). It just makes everything that one bit easier and it's as if it knows what you want. All the things I have thought would be a good addition to an interface is included in the iPhone. For example being able to categorise your apps and put them all in one place for you to find later. This, coupled with the fact that O2 were offering some great deals on the iphone 4s (unlimited texts and calls, with 1GB internet for £36 a month), made me opt for the iPhone 4S rather than the HTC I had previously planned on getting.

I decided to opt for the 32GB version because then I could sell my iPod and just have one device with all my media on it. I'm pleased with this decision, as now I can carry all my music, videos and apps in one hand! If you don't have that much music to carry around then the 16gb version would probably suffice, but if you've got 1000s of songs you want to carry around then the 32gb or 64gb version is your best bet. I also went for the white version because it doesn't show up marks, grease or scratches whereas the black one does. Both colours though are sleek and look good.

Messaging on the iphone is swift and simple. Even normal texting is like instant messaging and the iPhone's iMessage (which allows you to send messages and pictures to other people with iPhones without using your text allowance, and instead using wifi or 3g internet) is even faster. It's enabled me to send texts much quicker whereas with my HTC it could sometimes feel like a bit of a chore. I would be very unlikely to have long conversations but with the iphone I find myself having full conversations as if the person was here with me, sending and receiving hundreds of texts an hour sometimes! This is great for uni when sometimes the person you are contacting can live on the opposite side of the country. Another great addition with the iPhone is FaceTime, which allows you to video call other apple devices. This is great for keeping in contact with the family while you're living away, or keeping in contact with friends that live anywhere in the world! The video is crisp and clear, surprisingly good for a phone and better than a webcam which could be used for similiar services on, for example, skype. With the 4S's new 8 megapixel camera and 1080p (HD) video recording, you are sure to be impressed!

Calling is simple, and with the addition of Siri you needn't lift a finger! Simply request to call such and such a name and the phone will do it for you! The sound of calls is great quality and a real step up from my old HTC (I had the HTC legend which is relatively outdated now, so this isn't a criticism on the current lot of HTC phones).

Surfing the internet is where for me the iPhone really is a step up from the rest. It's quick to load, it's easy to zoom in and out, you can easily select text to copy and post onto other apps or text messages. Everything you could want from a phone is here, right at your fingertips.

Where the iPhone really stands out though is in its app store. While other phones may boast better processors (although the effect on performance is really, minimal) the iPhone boasts a better experience because it offers you more than other phones. More games, more apps to make your day easier, more education, more everything. There's something for everyone in the app store and thousands of things to help you stay productive throughout the day!

If deciding between the iPhone 4 and the 4S, I'd ask yourself what you are really looking for in a phone. The 4S is slightly faster and has a better camera, and has the addition of Siri. However if none of this interests you, you would probably be better going for the 4 and saving a few pounds. Siri itself is more of a gimmick at the moment, and while it is fun I don't often find myself using it. If you are one that really likes to keep up to date with their phone though you may want to hold off until the iPhone 5 arrives, projected to release by the end of this year!

Really I couldn't ask for more from my iPhone. Until something new comes along that really blows the iPhone out the water, as Apple originally did when the unveiled their phone in the market, I can see that I will be sticking with Apple phone devices for a long time to come.
