It takes a second to load up but it should show your gmail accounts as well as options to create a blackberry email account. This is where you went in to add your gmail accounts.
Select your gmail account and and hit the BB button. Select filters. In the filters screen click "Add Filter". You have to name the filter, I just put "gmail emails". For Filter On select "From Address" and for Contains type in your gmail address. Then click Add. So, you just told your device to block any emails coming from your own email address.
So I tried to set up filters...and I do not have that option on my device. I did a little digging and it appears that I need to have BES and i do not have that. I have Gmail, a storm and hacked for Tmo....how can I get these annoying double emails? Anyadvice would be greatly helpful. thanks
