A640 - Transfer Text Inbox

I have an A640 and I'm about to trade it for a a900M (they had a 640, liked it, and don't really care for the 900), but I want to transfer the texts on it to my computer or the 900. From what I've seen, PC studio doesn't support the A640, so it seems as though I'm somewhat stuck. Searched around here, but after going through so many pages I figured it best to ask. Any ideas as to how I can get the texts, or transfer them to my new phone? Thanks.

I seriously doubt its possible.
