Elm has a 5 megapixel camera, microSD memory card slot, and FM radio.
Upon release, the phone was available in two color schemes: black/silver (matte-black frame with silver-coloured battery lid), and pink.
The J10 variant has a second video call camera on display side, whereas the J10i2 features A-GPS and Wi-Fi.
The phone is one of Sony Ericsson's earliest environmentally friendly "Greenheart" range, featuring devices made of recycled materials, longer battery life and low-energy chargers, as well as minimal use of paper through reduced packaging and the replacement of the traditional printed user manual with one stored on the phone.
[4] Eco-rating, an organization providing sustainability scores to mobile devices, gave Elm 4.3 out of 5 rating, which is the highest among the handsets it evaluated in 2010.
