LegalTech iPhone Session - Call for Apps

One of the sessions I'll be helping lead at this year's American Bar Assosciation Tech Show is a roundtable discussion of practicing law with an iPhone. In addition to discussing network and security issues, I also want to highlight some of my favorite business related applications. At some point I will post a listing of the top applications here but in the meantime, I'd like to hear from the readers about what apps you find helpful for getting through the work day. OmniFocus and Evernote are the easy ones. Surprise me with something I've never heard of. Sound off in the comments or drop me an email.
