Hard reset: Press and hold both left and right softkeys, then stick the stylus through the reset hole in the bottom. You'll get a message about pressing a certain key to clear, then space to boot.

BUT FIRST!!!

Backup: Best application to do a backup with for the important stuff is PimBackup. Just google search it and install it to your phone by connecting your phone to the pc, let active sync on your computer connect to your phone, then click the explore button. Drop PimBackup from your pc into your my documents folder on the phone. Then on the PDA, launch file explorer and find PimBackup in your My Documents folder and tap it. Checkmark everything on the first two screens (You'll need an sd card in your phone for it to back up to). Might also want to click the custom line on the first screen and select options below. Tell it what files / folders you'd like backed up too. Then after your hard reset, start back at the beginning of this paragraph, but instead of selecting "backup" on the first screen, select "restore" and point it to the backup you made earlier on your sd card. It will restore your contacts, call logs, messages, and any files you selected to backup.
