Samsung SPH-M250

From Legacy Portable Computing Wiki
Samsung SPH-M250 prototype flipped open and powered on

The Samsung SPH-M250 is a clamshell phone that first leaked to the press in June 2006. Its rotating screen stood out compared to other Sprint offerings, and it was estimated the phone was being used for mobile TV testing[1]. The phone itself calls this TV service "Sprint VUE".

Aside from the brief publicity generated by its FCC approval, the SPH-M250 saw no public announcement from either Sprint or Samsung. The phone was never released, and only one prototype is known to still exist.
