So, we’ve shown you a handful of fun themes for your new E71, and highlighted a few applications here and there. However, alot of you are reporting issues with installation, so I figured it would be good to put together a walkthrough of sorts.

First, the basics - your Nokia E71 is using S60 3rd Edition, Feature Pack 1. You may also see this written as S60v3 FP1 in some places. This means you can install and use any application written for S60 3rd Edition. These themes and applications usually end with ‘.sisx’ or just ‘.sis’, and can be found all over the internet. My favorite place to get applications, though, is the S60.com website, which has a great Applications directory.

To install these applications and themes, you can simply Bluetooth the file to yourself, or store it on your phone’s memory card, and use the File Explorer application to navigate to the file, and simply click on it to open. Installation will start immediately, and you’re all set!

But wait, what if you get an error? There are 2 reasons you may get an error, with 2 very simple solutions. The first is if your phone is set to restrict the types of applications that can be installed, and the other has to do with the certificate used to sign the application or, more frequently, the theme.

The first thing you should check is to make sure that your phone is set to allow any application to be installed. To do this, you can go into your Installations folder, and open the ‘App Manager’. Now press your left softkey to open the Options menu, and arrow down to ‘Settings’. It’s completely safe for you to change the first option (Software Installation) to ‘All’, instead of ‘Signed Only’. Once you have done this, try to install the application or theme again.

If you are still having issues, it could be due to the expiration date of the certificate used to sign the theme or application. To resolve this, simply go into your Settings and change the date of your phone to 2007. Now, proceed with the installation again, and don’t forget to change your clock back when you’re done!

You should now be able to install nearly any application or theme on your phone without any issues, as long as it is a signed application. Unsigned applications are a bit different, and I’ll cover a workaround for those soon.
