Half Of Japanese Male iPhone Users Keep Their Japanese Cellphone
Nikkei BP Consulting and AdMob ran an online research to 1,000 Japanese iPhone users. The result [J] tells that 49.4% of Japanese Male iPhone Users have two or more cellphones.
On the same research, male:female ratio is 72.3%:27.7%. Web-tan Forum [J] who reported excerpt of this paid research did not mention how much of female iPhone users keep their second cellphone.
[Update] 1 in 5 Japanese cellphone users have second (or more) sub cellphone(s), another research says. So I can tell that more Japanese iPhone users need to have a second cellphone, probably a Japanese cellphone to keep using the closed cellphone websites and app stores.
