The bar along the bottom of my emails that allowed me to delete, forward, move to a folder, etc. has disappeared and I don't know teh instructions to get it back.
1. Is your device jailbroken, and if so, did you install any themes or other tweaks that could have affected the Mail app?
2. Have you tried rebooting your device?
3. If your device is not jailbroken, you may have to restore your device or go to Settings - General - Reset and then select "Reset All Settings" just in case a corrupt setting is to blame.
