I was barely on my phone the day of the usage. Only about 3mb was used as 'foreground' data but almost a full gb was used in background..in 1 DAY!. Half my usage is gone with almost a full month to go.

Could it be Firefox Sync??

Sync won't use a GB of data. What pages did you have open? Have you been watching a lot of Flash video?
