In December 2010, I took out a 24 month contract with 3 mobile for the iPhone 4 (16GB/Black). For me, it was the most expensive phone contract I had ever taken out and the first time I'd opted for a leading model (normally I just go for the cheap option!).

Upon arrival, the iPhone was packed in a small white box and was more or less ready to use immediately. I had to insert my new micro-sim (for those who are not aware, the iPhone uses a smaller sim card than the traditional sim). I did actually find the sim card tray and pin very cheap and delicate, they looked as if they would snap at any moment! However this passed with no problems and I've not had to remove this to the day, 6 months on.

As I'd never had a smartphone before, the whole touch screen aspect was exciting enough for me, so you can imagine my excitement once I ventured into the app store! The iPhone comes equipped with very basic, minimal features. The idea is that you visit the app store and personalise the phone with what things you use. After installing the latest popular games, I spent the next few hours playing 'Doodle Jump', a very simple and very addictive game! The app store is a great feature, it means your iPhone can constantly be updated with the latest software and gadgets, so in theory will take longer to become old fashioned. Older mobile phones can become quite outdated within 2-3 years. I'm hoping that this iPhone will last me a good 5 years.

Although this may be common sense for such an expensive piece of equipment, I would advise anyone who is considering purchasing an iPhone to ensure they have a case or cover from the start. I have seen some really good cases that cover the whole phone, front and back, and still allow the touch feature to work. I currently have a £4 blue rubbery cover, just covering the rear of the phone, which I picked up from Camden Market. The screen is quite scratch resistant if you take care of your phone, but I've seen some people with screens in dreadful condition! My friend dropped his iPhone very softly on the floor, which resulted in the entire screen cracking. Unfortunate, but a timely reminder that disasters can happen.

The 16GB memory for me has so far been very sufficient and I'm not even half way towards filling this capacity. I have around 250 songs saved onto my iPhone, which pretty much acts as an iPod for me too. For me the music player is the most used extra feature of the iPhone (this comes built in).

The video playback is really surprisingly good. It is so clear and define, it is almost as good as watching the TV itself. The sound playback is equally as good, making the smartphone a great entertainment portal.

The iPhone 4 is the best purchase I've made, since purchasing my first desktop PC. I would recommend it to anyone who can afford it. I cannot provide a comparison to it's predecessor the iPhone 3GS, so this may be a good starting point for those on a tighter budget. I've heard that the iPhone 4 is noticeable better though!
