First of all though is that you need an Android or Blackberry smartphone and I guess the rest may come in time. In addition you also can receive some drug interaction 
information as well. There are a bunch of applications that provide that information. If you have Verizon as a carrier then you know you can add on via their VCast applications which pretty much does it on auto pilot. I have been using Epocrates as a consumer for years and I think I will stick with it and you can also use the Epocrates link on this site to research drugs.
I am wondering if the program is going to tell you to go to Medco where it is cheaper to get your prescriptions via mail order:) To use the program you do have to enroll online at the Medco website. Last year Medco also bought another company that the FDA can outsource with for research related to device and drug approvals.

Computerworld – Verizon Wireless and Medco Health Solutions today released a mobile application that guides BlackBerry and Android smartphone users to locations where they can purchase the lowest-cost prescription drugs.
Verizon said the new Medco Pharmacy mobile app can also identify potentially harmful drug interactions based on Medco members’ medication histories.
The Medco Pharmacy mobile app is built on Medco’s My Rx Choices prescription savings and patient safety program, which was launched online in 2006. To use the app, patients must first register at the Medco website. Once registered, their medication histories and drug plans are made available online.
