I read here (http://mail.google.com/support/bin/answer.py?hl=en&answer=77702) that when setting up Gmail on an iPhone, it automatically sets it up as IMAP if you select the 'Gmail' icon. However, it warns that archiving and deleting messages will work differently, and it says that deleted messages get sent to the Gmail Trash folder and automatically deleted after 30 days. That is actually what I prefer, because I like keeping my mailbox free of clutter. My question is this: With Gmail setup on your iPhone in this way, is the Trash folder the only folder that automatically deletes messages after 30 days? Thanks!
