Recently I was reading about different tech tips to make my life easier. Seriously I am not a techie person. Last week somebody sent me a file with a file extension mdf. It took me awhile to open it which is really a bummer. Anyways I just bought a new mobile phone and it currently uses Symbian OS. Actually it is a smart phone with greater functionality. It is a cross between PDA and mobile phone.

This phone also uses file extension sis which I think is quite complicated. I had to read some articles about installing sis on my phone. The sis is an installation file for symbian OS platform. It is said that the proper application is .APP file. This is generated when installed in mobile device. There are several steps that you need to apply so you can get the application installed and that makes it hard for me to remember. It is also confusing as well. You need some tools in order to create files. Some of these are createsis, makesis, makekeys, and signsis. These terms are really not for me that is why I need to ask for a professional help when it comes to uploading files in my smart phone.
