Yahoo on Tuesday said it plans to once again boost its free e-mail storage limit--this time to 1GB, the same amount offered by archrival Google. Beginning in late April, Yahoo will upgrade free users to the new storage limit of 1GB, up from its current 250MB. The company said it will take about two weeks for all Yahoo Mail users to see the boost. Hotmail still offers only 2 MB(250 to some users) in it's free web mail service.
