I've been using the Samsung PC Studio 3 since July of 2009. Every time I want to clear out the messages from my phone, I copy them onto my PC first, then delete them from my phone. After doing that for months, I've always had a backup of all of my old messages. I went to clear out my inbox today and look through my old messages, and I realized that the list of messages only dates back to the beginning of the month. I don't know where the rest of my messages went. I'm wondering if I just deleted them by accident or if there is a limit to how many the software will store on the file?
