I saw here in an article from yesterday:
that the chinese vendor yulong anounced a smartphone
to use 2 GSM cards simultanious:
(site not reachable at the moment)

So maybe 2007 time and market for a Neo1973-Dual?
Could somebody confirm that GPRS is only active when you do not phone
via GSM? So that you can't phone with somebody and use a GPRS connection
to your server?
