What's wrong with my ENV 2?

It won't charge or anything. I think it might be the charge inplug on it that's messed up, or it might be the battery. It stopped working in September or October of last year and I found it maybe a week or two ago, and I really want my old phone back. I have an Alias 2 now, and I love it, but I really want my old ENV 2 back. PLEASE HELP?
