I would like to know the same thing. Here is a list of my apps. I dont know what most of them are. Some I use, some I think I use, others I have no clue. I only have 29mb of internal storage. I have tried everything to use a2sd on my phone. Nothing seems to work. So, I need to thin out my rom and get a little more streamlined. Any help would be greatly appreciated.
