sorry to hear 3110c not working for you infra, but I really dont like joystick in W200i, I dont know what will be the price of W350i when they release it here,
and hari whoever was selling you 3110c in 6K for boxxed is certainly a crookhead, because its price is lower, even 3500c comes for 5.8K that to from Nokia pririty dealer, 3110 is nothing bad for a general phone and if you count the features it really is what you will want in that price. SE should have given bluetooth in W200i very bad design decision I would say.
And add to it they have put joystick, and I say joystick in SE phones are crappy.
I say bluetooth is a must in new phones, but except for the joystick I dont have anything against W200i, its a great phone.
And I see 3110c working very well with me, add to it, it is used by my team for handling client calls, and its going on really well.
