first of all , this phone is for people switching from a regular cell phone to a better interface. second, t-mobile does not require you to join a 40$ a month data plan. you can simply get a regular plan and pay just phone charge and use the calander, music player, games etc...just no email and internet. (that's 2000$ of saving compare to iphone)..if you want the extra internet , you can get a $24 3G data plan...way cheaper than ATT and verizon.
the phone is small...it rings loud and call quality and reception is good. (unlike iphone...my reception is really bad)...it does well on it's primary function...a phone.
As for browser..yes, all samsung phones use the same crappy browser that slows down the 3G connetion. (I had samsung instinct on sprint and it's the same bad browser on a fast network...GPS downloads quick on that phone...so it's the browser problem).
however, you can download a third party browser to use on this phone...your experience will be much better...
screen is small ...not as good as iphone but you get a small phone to carry around.
my wife has this phone and after comparing with my iphone, I think it's as good as it get for this price range and without the killer
contract price with ATT or Verison.
