Yes, right now Tmobile is the last National carrier that allows free hotspot browsing on (some, not all) smartphones, but as they are the last, this can change at any time, so don't count on it forever.

Also you will be able to use the "Hotspot" browser, not the "Blackberry" browser, and remember you will not be able to use the Blackberry functions (push email, BBM, etc) unless you get a BB data plan. The Blackberry phone will allow you to connect to the internet, and go to websites, but alot of what the Blackberry does will not work without "Service Books" sent from the carrier (Tmobile) to your phone.

Rest assured, right now, if your phone connects to the internet on wi-fi, with or without a sim card, it doesn't matter, it will work either way, Tmobile will not send you a bill for data use.

Now, all the other carriers (Verizon, AT&-T-, Sprint) will find your phone connected to the internet, and start sending you bills (or just not connect at all) in a New York second. So remember it's only Tmobile phones that do this. So don't tell other friends with smartphones on other carriers that they can do what you do. What will happen to them will be just ugly if they try.

PS: Don't worry about using the wrong browser (Blackberry) because I'm pretty sure it won't work without "Service Books"
