Welcome to Pocket PC Addict! Let's see if we can help you out. I don't have an sp5 but I can tell you that my old sp3i's SIM Manager was under the Accessories folder. What's in yours? Also, I'm not sure what you ask asking when you say you want to update the virus files. Are you talking about updating virus definitions? If so you need to get an Antivirus program for your smartphone first. If you are looking for one you can download Trend Micro Mobile Security
here. Let us know how it goes!
