You can read the pros for this phone in many other reviews or in the specs (lots of good features, nice camera, good speakerphone, etc). I'll just mention some cons and some things that annoy me personally:-First, as many reviewers have mentioned, the phone does tend to DROP CALLS after 10 mins or so - all the time. It did so at the beginning, but after I turned it off and restarted it several times, it stopped and works fine now - very few/almost no drops now. So try that if it happens to you.-The phone may be a bit bulky for some - plus the antenna adds to the bulk.-I dislike the "Vibrate THEN ring"; why can't it ring and vibe at the same time? (personal irk). In the same line, the "smart button" can be annoying. If I have the phone in my pocket and happen to press the volume control, it remains in that screen until it is repressed - the prob: if you press the smart button first, it will switch the ring style -i.e. it can go from vibrate to loud without your even knowing. it'd be nice if after a while, the ring style change just disappeared on its own.-I hate the fact that T-mobile phones only have 8 true speed dials (2-9; 1 is always reserved for voicemail).-phonebook: can't store more than one # under same name - it'll add another entry, and if you are searching in phone book, may be confusing.Overall, good phone, with some minor irks. the biggest concern should be the dropped calls. T-Mobile service in nyc seems decent - no major probs that I've noticed.
