Just upgraded from the NTT Docomo N503i to the FOMA SH700i mobile phone (keitai 携帯）complete with bar code reader (essential nowadays), imotion and silly whizzing noise as you close the handset - I hope there's a setting to turn that off. The imode screen is certainly brighter and more attractive and having a camera (1.3 megapixels 3.7 mm 1:2.8) is fun. To save images to disk there is the option of installing a miniSD chip to your phone and a USB reader to your computer to view images on your PC.
