Google Docs went mobile a little over a year ago, but only let you view the documents you had made on your desktop computer. Well, Google Docs Mobile has recieved a little bit of a feature upgrade,now allowing you to edit, sort and filter existing spreadsheets on S60, Android and the iPhone. This is a great option for small and medium businesses who need to fill out expense reports on the go, but don’t have the coinage for a catered mobile application. BlackBerry support is conspicuously absent. Humbug! Hit up m.google.com/docs on your mobile browser to have a go.
