iOS (iPhone/iPad) icon sizes and names explained

So each device type/size combination should have 2 icons:
the Application icon
the Spotlight/Settings icon


Additionally you should have an iTunesArtwork File but its not required.  Technically the only "required" icon is the Application icon.

Original iPhone/3/3s/iPod Touch icon sizes and names:
Icon.png (57x57)
Icon-Small.png (29x29)

For Retina icons for the iPhones & iPods we double the resolution in both directions and add "@2x" to the name
Icon@2x.png(114x114)
Icon-Small@2x.png (58x58)

For the iPad 1 & 2 we need the same icons but they have different naming requirements
Icon-72.png (72x72)
Icon-Small-50.png (50x50)

And again, for the new retina iPad we need to make "@2x" versions so
Icon-72@2x.png (144x144)
Icon-Small-50@2x.png (100x100)


So, for a complete universal app that supports all screen sizes you want to create:
Icon-Small.png (29x29)
Icon-Small-50.png (50x50)
Icon.png (57x57)
Icon-Small@2x.png (58x58)
Icon-72.png (72x72)
Icon-Small-50@2x.png (100x100)
Icon@2x.png (114x114)
Icon-72@2x.png (144x144)


Additionally you'll probably want to make the iTunes Artwork icons
iTunesArtwork.png (512x512)
iTunesArtwork@2x.png (1024x1024)

Mono for Android Installation problems on Windows 7 with VS 2011 Beta installed

I just recently decided to experiment with Mono for Android (www.xamarin.com).  I had no problems installing it on my Mac Mini running Lion but I had no luck with my Windows 7 laptop.

The installation would appear to complete successfully, and I would see the SDK from within MonoDevelop but as soon as I'd try to create a project I would get the pop-up stating "Mono For Android is not Installed."

Additionally, every time I ran the Mono for Android installer it would tell me it wasn't install (but all other prereqs installed correctly).

After several re-installs I noticed devenv.exe for Visual Studio 2011 Beta was constantly running. 

So I'll cut to the end, I needed to fully uninstall Visual Studio 2011 Beta, uninstall Mono for Android, and then re-install.

Now everything works great.

For reference I'm running Windows 7 Professional 64, I have Visual Studio 2010 Ultimate installed (thank you Bizspark) and I installed Mono for Android 4.2.2.

Happy coding!

Panoramic Software Inc. launches Calc Pro 3.5 for iPhone / iPod Touch

Panoramic Software Inc. has just released Calc Pro for the iPhone and iPod Touch - I know a lot of people have been waiting for this.

Its very similar to the Windows Phone 7 version but contains a few improvements - most noticeably is the updated Date and Time calculator which has been redesigned and now shows the moon phase for the from and to dates.

It also of course makes use of the native Apple controls. It's normally $9.99 but its launching at 99 cents so its definitely worth grabbing now.

You can see it on the website here:

Calc Pro HD coming soon for the iPad

Samsung Focus Unlocked

I recently unlocked my Samsung Focus from Rogers Wireless so I can use it with my pay-as-you-go T-Mobile SIM while travelling in the states.

You can find lots of information on unlocking but since I had such an easy experience I wanted to let others know that I got an unlock code in less than 8 hours from www.Cellunlocker.net and it only cost me $8.

I haven't tried any other services but this one was cheap and simple. They also provide really straight forward instructions.

I was also able to use the t-mobile sim and access data without entering any additional settings. I also came across a forum post the stated a hard-reset was required after unlocking - that definitely wasn't the case for my phone.
