E 90 keyboard

E 90 keyboard

Hello,
I working in the South Caucasus FETP program and we are thinking to by the nokia E90 to develop a survey and outbreak investigation, but we are not sure if the Episurveyor recognize the inside keyboard or if just the outside one. Because the idea is improve the ergonomics of the typing process. If not will be cheaper by other simpler models.
thank you
