After a week with my iPhone 4 I’m still amazed by the new retina display. It is gorgeous. The only problem was my application icon for the Followers app. It looked rubbish as it was simply doubling up the pixels of my old iPhone 3 icon.

By default the old icon is 57×57 pixels. Doubling up for the retina display requires a new icon of 114×114. Whilst the on-screen size is the same you get the retina effect due to 4x the pixel count in the icon. What’s really clever is the way that Apple handle the addition of the new icon. My existing icon was called Followers.png. To add the hi-res iPhone 4 retina icon you simply call it the same name as the original icon and add @2x to the end which gives me a second app icon file called Followers@2x.png.

To complete the full set of 4 icons I also doubled up the search/spotlight 29×29 icon. This gives me 4 icons covering both retina and pre-retina iPhones with sizes of 29×29, 57×57, 58×58 and 114×114. Full details, including the iPad icons which I haven’t included yet, can be found in the Apple reference library here.

I still have several other images to upgrade for the iPhone 4 before I release an update to the Followers app so in the meantime here’s a comparison of the two app icons side by side.

Visual harmony has been restored to my iPhone!

So, after many weeks of indecision I finally decided to go and upgrade my old iPhone 3G for a shiny new iPhone 4. I popped into the local O2 store today and did the deal. And what a deal it was.

As I was comfortable in continuing my £35 a month contract I snagged a 16GB black iPhone 4 for £119. Not bad. However, when I came to pay the assistant she asked if I wanted to sell my old iPhone 3G to O2 – for £154! Seriously, this is a 2 year old 16GB iPhone 3G that I originally paid £159 for and they offered me £154 for it. That’s a paltry £5 depreciation over 2 years. I left O2 with a brand new iPhone 4 and £35 in my pocket. Brilliant.
