3D is just another buzzword to suck people in. Recommend you not to buy such tech when its not widespread/cheap. AFAIK, only two (major) phones have the dual cameras necessary for 3D video recording: HTC EVO 3D and LG Optimus 3D. Neither of them are worth it.
OS depends on what you need: the ability to tweak to your hearts content, to change the OS to your requirements (Android), or use it as-it-is, for a straightforward experience (WP).
I say go for HTC Sensation (Android), or Nokia Lumia 800 (WP).

2. Go for a phone which will have bluetooth v3.0 for good transfer rates.
3. Buy an NFC enabled phone as it is said to be the future.
4. Go for Samsung brand as it is coming with successful phone models and built quality.
2. BT 3.0 in itself is no good. 3.0 + HS certification is a must for faster transfer rates.
3. Nokia's pushing NFC like mad, SGS II has it as optional (I think), Sony Xperia S is supposed to have it, and there ends NFC in India
. The main way NFC was intended to be used (as ID while paying) isn't implemented anywhere (correct me if wrong).
4. While Samsung's build quality is good, and the phones themselves are great, their fickle decision making and attitude towards customers concerns me. Case in point: Samsung Galaxy S was denied ICS (even though its perfectly capable of running it), then promised a value pack, then denied that too, then rolled back and assured the value pack. Not just Samsung, most manufacturers tend to forget you after you buy their phones...
