looks like 2100, but certainly it will attract many people to buy it. It's smaller, has more features, looks nicer, have better resolution than 3510i/3530. Nokia gonna control the market with this and 6/7 series colour phones!!!
They are 1 because they flood the market with phones and Nokia FANS keep wanting every one of them =P.. LoL..
They all have the same technology with different design ONLY. But I think that the 3100 is something different... after how long. LoL.
If you had brain instead of shit in your head you would see the value of those phones.
