Some phones use a "Trash Folder" system so you can retreive deleted emails within a certain window of time. I am not sure on the Bionic.
Also you could possibly retreive your mail directly from your email providers server. Example I use charter email, so I would contact charter communications, gmail is Google so you would contact Google, etc.
Good luck.
If you are referring to gmail, go to the gmail website and instead of looking in your "Inbox", check your "All Mail" box. You should be able to check this mailbox from your phone, too.
