Head down to the Charles river (between the Longfellow bridge and Massachusetts ave). They let off fireworks from a barge in the middle. On the banks of the river you will find a couple of million people partying. But bear in mind that drinking alcohol in public is super illegal here. So don't turn up with a box of beer.

Last year, we spent a brilliant time with Manny in the Boston YHA - he did a huge meal for all his guests and took donations for charity.
Other than that, we went for a wander around the town and nothing was open. If you plan to drink some beer, buy some the day before as - again - none of the shops are open :)
