AFAIK "Benefon Twin Dual SIM" was the first phone that allows the user to switch between two SIM-cards with the phone GUI. An open Smartphone could make it possible to swith the SIM automaticaly to get the cheapest scale (tariff) before dialing/dataconnection/sms sending.... And even for caller - when your frind/partner knows about your phone, you could reject the incomming call and switch to another GSM-net by choosing another SIM. HeShe has just to call a second time... Going abroad - I live in Aachen, is close directly to the Netherlands and Belgium (just to walk 2 km to the south or to the west). Beeing called with a German SIM is very expensive for me. E.g. I would walk/drive to Belgium - the Neo1973 could check with A-GPS which card to use next, when my phone is going to lose the contact to my German GSM-network and choose the right (cheapest scale) card for Belgium. Also for travelling by plaine - switch on, and the Neo1973 will check with A-GPS which SIM would be the best (of course it would maybe the wrong card to be able to use A-GPS - but (optional) it could reject incomming calls at that moment). A-GPS could work more accurate when you use more cell informatios - or your GSM-net offers only one cell connection because this network is not good/strong at the location you try to find it's coordinates - just switch to a foreign gsm network and you have the chance to use roaming to more gsm networks.... You have several SIM cards? Neo1973 could swith to different networks automaticaly from time to time to collect your incomming SMS from other networks. On scale/tariff better on the afternoon/nigth, another better on a weekend - let your software switch atomaticaly. Last idea for the moment - with asterisk with to numbers on asterisk you could log off on asterisk before switching and log on after so that asterisk knows how t forward calls to you AND gives a busy as feedback for incoming calls inbetween. So you would not lose any incomming calls. So when the circuit board of the Neo1973 got some additional solderpoints, someone like to hack an electronical switching for 2-8 sims (maybe to extent the cace by 3-4mm). Networkprovider wouldn't like such features - but hey, when the Neo1973 is distributed without their shops anyway why not make the Neo1973 more smart, especialy with features that GSM networkprovider never would sell? Keep in mind that a lot of unsuported things in mobils of today where not the lack of creativity of the developers - it was grabby whish of the business people of the netprovider, shortsighted in my case - without a smart SSH and other features on my phone that makes it real to a smart phone smartphone = mobile computer + GSM/GPRS I have no need for GPRS e.g. and I would not use the Internet, when Compuserve/AOL is the only one who sells network connections and terminals. So beside of the dumbphones of today - there is so much potential with an open smartphone :))) I realy hope that here will be at least *one* usable SPI connector on cicuit board of the first Neo1973.
