Another new entry-level cellphone from Sony Ericsson today, the J100 is about as low-end as a handset gets these days (at least from a major manufacturer). This one's a dual-band GSM phone with specs that are positively retro: a 96 x 64 pixel display (ouch!), polyphonic ringtones, and, well, that's about it. Will come in three versions: the J100i for Europe, the Middle East, Africa, and Asia Pacific, the J100c for Mainland China, and the J100a for the Americas. Should be available sometime next quarter.
