For easy access.
This is my iPhone’s home screen – you can see the icon for ‘PP&P’ in the third row.
To add it to your mobile device, go to my blog in Safari by clicking here, touch the rectangle with the arrow in Safari, then touch ‘Add to Home Screen’.
Touch the circled icon on the iPhone.
On the iPad it’s to the left of the site’s address bar.
Then touch ‘Add to Home Screen’
You can name the icon whatever you want – I call it ‘PP&P’ for brevity – and move it wherever you want in the usual way.
Thereafter, touching the icon will take you directly to this blog’s index page on your iDevice.
The design of the logo is addressed here if you want to make your own for your site.
