I myself have got a Nokia 3650.
But I would strongly recommend Nokia 6610 or 6100.
If if you're looking for fancy camera mobiles, I would recommend Nokia 3660, which a better version of the one I've. But there's also Nokia 6600, which without doubt is top notch.
But I would go with Nokia 6610, if I had to lose my mobile and buy a new one. Hope that necessity doesn't arise.
And I won't ever in my life buy a mobile other than Nokia.
