There has always been a conflict between my personal and working life over the subject of a mobile phone. My employer needs me to have a mobile phone, and provides it (well, at least the SIM! And a ‘free’ handset to a reasonable value too). I also value having a mobile phone of my own; but I don't want to carry two.
Therefore I have to use just the one incoming number – it belongs to work, not me. And my outgoing personal calls have to be separated out from the work ones for expenses purposes, too.
I've been waiting for the sensible option – a phone that can hold two SIM cards at the same time. That way, you can differentiate between personal and work calls both incoming and outgoing; and if you change employer you don't lose all your contact data and have to change your number!
While reading a post about the OpenMoko GTA02 getting into production, I spotted a google ad for “Dual SIM phones”, and ended up on a page from a Malaysian company, DuoSIM. It looks like the world is finally catching up on what people really need from their technology, eh?
(Now, what will be more fun? An OpenMoko Neo FreeRunner or the new iPhone? Both with Wifi, touch screen, bluetooth, GPS, accelerometer, similar battery life; the iPhone has significant data storage that the Neo doesn't (but it will take microSD), but has a mostly-closed development environment …)
