How to test if your site is mobile friendly.
There are a number of emulators where you can test your site to see how it views on PDAs iphones imodes etc.
Operas PDA Simplator https://www.opera.com/mobile/demo/
Iphone Simulator https://www.testiphone.com/ ( bare in mind this does not support horizontal mode )
A downloadable iphone exe emulator for your PC ( https://www.technixupdate.com/iphone-drift-surf-with-iphone-safari-browser-on-windows-iphone-emulator/ )
If your site is looking broken on these devices it reflects badly on your company.
