GSpaceMobile is a freeware application that lets you use your Google GMail account as a local file system on your Nokia S60 mobile device. It integrates your GMail Inbox as a remote network drive on the device and allows you to transfer files to and from your mobile phone as attachments.

Local files on your phone can be uploaded to your Gmail Inbox, while remote files in GMail Inbox can be downloaded to your phone and cached on the phone’s memory/storage card. This tool is compatible with the Firefox addon called Gspace. With this extension, you can upload files from a desktop computer and download them to your Nokia S60 mobile phone, and vice versa.

To use GSpaceMobile:

1) Launch the application
2) Add a Gmail account
3) Select Memory card for caching downloaded files.
4) Login to Gmail account
5) Start Uploading/Downloading Files
