When you are travelling around, it can be hard to stay up to date with the latest movements in the currency market, as you are often miles from the nearest internet-connected PC. However, if you have a smartphone such as a Samsung Blackjack, a BlackBerry, or a T Mobile G1, then you are in luck, as there are free currency converters available for all of these machines.

BlackBerry users should try and get hold of an app called Worldmate Live, which is available from the BlackBerry App World service. You will need to download App World to your BlackBerry first. This requires a trackball and a BlackBerry operating system version 4.2 or later, and takes around ten minutes to set up. After installation, simply go into App World and search for Worldmate Live. The app itself should take no longer than three minutes to set install after downloading.

Worldmate Live can boast up to date information about over 160 currencies, plus weather information, an international clothing size comparison chart, and an itinerary organiser.

If you have a T Mobile G1 phone, then you might want to give aCurrency a go. It is completely free, only takes a minute or so to install, and can give you up to date info on more than a hundred and sixty currencies.

You can download aCurrency directly onto your phone via the Android Market, Googles own version of the iTunes App Store. You can get it by searching for the word Currency and then clicking on the aCurrency download when it appears. The most impressive feature of aCurrency is that it automatically updates itself every time it starts, as long as an internet connection is present.

If you have a smartphone, such as a Samsung Blackjack or a Motorola Q, that is powered by the Windows Mobile OS, then you are able to get your own version of Worldmate Live.

Simply go to the worldmate.com website, either on your smartphone or your PC, and choose to download this app to your phone through a link in an email or text message. It will take around ten minutes to download from there, but after that, you are ready to start checking out the exchange rates.

If you are travelling somewhere that lacks internet access, be aware that the currency information in your smartphone will not necessarily be up to date, as it will be basing its calculations on the data that has most recently been downloaded.If you need anything other than an approximation, make sure that you open the app while your device is connected to the internet.
