I want to be first to say this here. When this option is available on the iPhone the entire internet is going to be buzzing about it.

"The functionality that sets this BlackBerry Curve apart from any other BlackBerry device is the UMA T-Mobile HotSpot @Home support. Without this functionality I may never have tried the device and this support is actually what is driving me to a purchase of the Curve and activation of the service. HotSpot @Home now runs US$19.99 per month for a single phone and I believe US$29.99 per month for a family plan. It allows you to make and receive unlimited calls while you are connected to an authorized WiFi hotspot. This can be your home @Home or other router, T-Mobile HotSpot location, or other WiFi access point (even secure ones) where you do not have to enter information via a web page login (this may knock out a lot of hotels from being candidates). I may actually take along a WiFi router when I travel to setup a virtual HotSpot in the hotel room with an ethernet connection. I want to test this out when I travel outside the U.S. as I am very curious to see if I could make and receive calls internationally when connected to a compatible WiFi access point. That would be very cool to make and receive calls that appear to be from my mobile phone while traveling overseas."
