Moto E398 - The first phone in the mobile phone market with 'Music' as its main priority. The success of this phone inspired the 'W' brand from SE.
Been an owner for a year, now my little bro uses it. Its stereo speakers still remain one of the best, but the headphones really don't have that loud volume for music (maybe with a 3.5mm jack converter things may be different but this is not available anywhere in India).
And yeah, you can mod it and all, I did around 2 years ago to my E398 to V398, add a minute full of videorecording. The cam is VGA so don't expect much.
For Rs.3k - Its a KILLER phone.
