Hi ShmengeTravel,
Have a look at the following link...

and
www.enfora.com
I bought one here in Singapore from a local distributor for just under 400 SGD. I am still in the process of evaluating it so I can't give a detailed review on it yet.
Firstly it's expensive....it's a nice unit, about the same size as a CF Gps mounted card with an extendable aerial. The phone side of it worked out of the box BUT in order to receive calls the software has to be running!!
I didn't buy it primarilly as a phone (emergency only), more to be able to access the internet etc when no wi fi hot spots are around. I had a problem with the gprs set up because the sim card "pin code" was somehow blocking the dial in gprs system. Once I removed the code, took a long time to discover this, it functioned well.
Is it worth it ? The jury is still out! It's nice to have the possibility of internet access, but as a stand alone phone (software has to be on to receive) I'm not so sure, although maybe other systems don't have this drawback.
Regards
