I formatted my phone back to stock and when I signed back I ln to my gmail. It started redownloading all my Apps.grrrrr. and I noticed the background data box was checked. So I unchecked it. But when. I did it wouldn't allow my gmail to sync..before I had no problems having the background data off and still sync my gmail automatically. I don't know what happen. Maby I did something wrong to change some other setting?
