There's a new app available that will let you sign that PDF or Word document and send it off to continue business while you are on the go. This app is called Sign-N-Send. There are two versions - a paid app version for $2 that removes the 1 page Advert at the beginning of the document that is inserted if you use the free app version. I'm quite sure this is going to come in very handy for quite a few of 2K's clients that are always on the go.
