Slow down, breathe & re-write the question in well formed English sentences.
You may then get some answers. Your question is somewhat incoherent.

Start with :
-Win Phone 8.0 or 8.1 Dev Preview ?
- Which model (RM-xxx) ?
- WiFi ? Is your internet (@ home) working ? What security protocol ?
- Vibrate ? What's that bout ?
