With the iPhone4 , the iPad and the iPad2 with iOS4.3 you may have noticed a change to your email options in GMail.
There is an archive button not a delete option as there was before.
Well if you are like me you dont want to archive some mail messages so the question is , How Do You Get Delete Back?
Open up the settings tab on your iPhone or iPad and select Mail , Contacts , Calendar , then go to your Gmail account.
You will see Archive messages at the bottom of the settings.
Simply turn that to OFF , click Done and your delete option will be back.
