Thanks for your help. Sorry for the delayed response but my internet was down for about a week.
Anyway, happened to show my mom the LG KF510 & though she liked it, she's a bit apprehensive about the touch sensitivity being durable.
As to the W580i, we happened to see a peach/pink coloured dummy, which she liked a lot. But neither this colour nor the red one are actually available. Apparently, only the black one is available. One salesman even told me that the red W580i wasn't even launched in India.
So my request to all is to just let me know if the red/peach/pink W580i is available in Mumbai [maybe Lamington Rd?] & at what price.
The other phone she happened to like is the red+black W705i. She didn't like the shade of red on the W910i, though to my eyes the shade is the same as the W705i. Are they any different? We happened to see them at different locations under different lighting.
So guys, please help me out. Much appreciated. Ciao for now!
