PushL has released version 0.77 of Y-Browser, a free File manager/explorer for Nokia S60 3rd Edition mobile devices. This new version supports plugins to view Zip and Text files as well as a Mail Folder messaging addon/plugin that allows you to view files received on your mobile device via Bluetooth. I haven’t tested the messaging plugin but some users have reported it to show all messages in your Archives or “My Folders” folder.
