The table of 声優 who has used or is using an iPhone till Nov 22, 2013. 1
93 people in the db have an iPhone, including 声優御三家.(ほっちゃん、ゆかりん、奈々様)
And many 声優s own both an Android phone and an iPhone, e.g.:
- 内田真礼 → iPhone 4S | REGZA Phone T-01C
- 竹達彩奈 → iPhone 4S | SONY Xperia™ UL
- 加藤英美里 → iPad mini | SONY Xperia™ SX
They all like games, probably the best explanation. And for these 声優s who are fond of otaku’s have shorter cycles among their phones.
