Good news for you Foursquare users out there. Foursquare for BlackBerry was just updated, now supporting photos. You are now able to check-in to a venue and add a photo, as well as submit a photo to the venue you are checking in to. They also announced that they will be adding the ability to comment on check-ins via BlackBerry. This feature should be available within the next week or so. Thanks @MrCippy !!
