Advantages: Improved speed & battery life Disadvantages: Camera still lacks behind competition
Apple have improved on the Iphone 3G on their latest masterpiece, the Iphone 3GS. As well as all the advantages of the original Iphone such as a great user interface, superb internet capabilities & the ability to download an application for almost anything, the 3GS offers some new features. I would say the most obvious is the improvement in speed in general, you can definetly notice it when opening messages and using the various different applications. Also the battery life has been slightly improved but not hugely. Other improvements include a slightly better camera to just over 3 megapixels which is the only disappointment as it still lags behind the competition & there is still no flash or zoom capabilities. Also added is a video camera facility with the option of editing the videos on your device. Another improvement is a compass ...
Advantages: A great phone Disadvantages: None, in my opinion!
So, as I?m sure everyone on here who has an iPhone has done, here?s my review on this little beauty?just by that you can already guess, I?m a fan of this!
After my last contract with o2 expired three months back, I had the choice to renew everything and seeing as there was a distinct lack of phones available with o2 (in hindsight, I would have perhaps opted to look at the phones available with contracts provided by the Carphone Warehouse) I bit the bullet and went for the iPhone 3G 8GB version?the 3GS was available, but I?m not made of money and lets be honest, to pay that much extra for a bit more storage space, voice control and a video camera is not worth it in my honest opinion.
I?m sure you?re all aware of what it looks like, but if not it?s a touch screen operated phone which is a glossy black little number. A smooth back cover ...

Ciao members have rated this review on average: very helpful Review of Apple iPhone 3G
Advantages: It's advanced technology and huge variety of features. Disadvantages: The very low and quickly decreasing battery life.
The iPhone 3G S is an amazing piece of palm-sized technology. It has everything you could possibly ask of a mobile phone (except Blue-tooth data exchange), and much more! I was shocked at it's ease of use considering its a smart phone! However, although it does have a few new features from its predecessor, the iPhone 3G, but it didn't seem as much of a technological breakthrough considering the transition of the original iPhone to the iPhone 3G, which is one of the reasons I gave it 4, and not 5 stars.
First of all, there is the biggest thing about the iPhone 3G S, is the addition if the S to the title. It stands for speed, and they're not lying. I compared my friends iPhone 3G to my iPhone 3G S, and I noticed how much quicker internet pages load, applications load up, and even basic things like sending a text (which may have been due ...
