I have only good things to say about this device, every person I know who has bought one has said it is brilliant!

To top it off not only does it provide me with emails, calender updates and the ability to view amend and send documents but the built in GPS just tops it off as it can then navigate me to get to meetings too! It is called the V1615 on Vodafone, I think each provider renames the device but it is good to shop around on price however because I wanted the best data speeds I went with Vodafone.
