How can I install software in my Samsung E1410 mobile?

Just to add onto this, I personally prefer to use Opera Mini for a mobile browser. If you go to mini.opera.com on your mobile phone's built in browser, it will walk you through installing it onto your phone (all done directly on the phone), however Opera Mini doesn't directly support WAP downloading. What will happen is when you select a link for a WAP download, it will open a page saying "Save" and when you click that it will automatically open your phone's built in browser to initiate the download automatically.
