I bought Samsung Galaxy Ace mobile before 2 months and I would definitely like to recommend you, I got it in 11, 000. really good features phone.
Following features I really love:
5mp Camera,
supporting many online applications
All Basic functions(MP3, FM, Camera)
many in build applications(News & Whether, Places, maps, socail hub, Play store, google search)
Things I don’t like:
