Try this, if you'd like. It will free up a good bit of space. Before I did this I had about 1.3-1.5 mb's free depending on how many e-mails and text messages I had kept in the device. I just looked and I have 25.1 free now, with about 4 or 5 apps loaded and a couple extra themes.
If you arent computer/tech savvy (which I am not, at all) its not as hard as it looks. Just read and follow the steps exactly and you'll be fine. If you are savvy, then it will be a piece of cake. Good luck.
