Wtb: dual sim edge java phone under 4k

[phuchungbhutia]

Please suggest a dual sim mobile phone which has gprs edge - dont think 3g is available in dual sim at such price . It has to be java phone as i would like to install few apps like ucweb. Most imp is it should cost under 4k inr. I would prefer slim and smaller form factor since i want it as backup phone for my nokia 5800, but qwerty phones would also do. Also expandable memory , 3.5 mm audio jack , would be good
