Don't know what I did without it! – I have never been happier with a mobile phone than I am now... I have owned many over the years, all the same brand, but this time I decided it was time for a change! I am "over 50" and not terribly "savvy" with modern technology but found the apple iphone4 to be perfect for my use, both business and personal. And to add to this, the service and aftersales service I receive from my provider is impeccable. Easy to operate, reliable, great camera
