Food for reviews:
- Call quality (at least in comparison with your old phone(s), state what phone(s) you had :-) )
- Reception (at least in your area, copmare with previous phone(s), same as above)
- Maps: offline maps? turn by turn navigation? public transport layer? directions using public transport? zoom bar (+/- buttons as opposed to pinch to zoom)
- Mail (does it work? easy to set up? IMAP?)
- Messages (would be nice to see it working with integrated social services)
- RSS reader/feeds (generally how they work)
- Browser (a more detailed review)
