Ok, first this is not a JB update issue, I have had my phone for 2 weeks...and have had this before and after the update, I believe it is the way I initially set up my phone, wonder if you all can help. I used Gmail, and everytime I get a incoming mail, I also get an incoming mail from the native mail client. Maybe I set then both up at the start I am not sure. But it is getting annoying, everytime I get an email...I get 2. One from each...and I can't figure out how to get rid of the stock mail client. When I try to delete it from pulling Gmail, it says I need to have it. It is making me use the default client, when all I wish to use is Gmail itself. Ugh. Thanks to anyone that can figure this out short of doing a reset...
