I currently use the Samsung Blackjack from ATT. I really do like this phone but have a few issues with the technology. For some reason Samsung decided not to use a standart USB plug to charge the phone, they have their own connector. Also, they decided that you can’t charge the phone using usb power unless you are 1. hooked to a computer with activesync 2. the battery has some charge. This is just stupid, I can’t use another computer or my car usb adaptor.
Currently I am at a point where I find my Blackjack a required item to take with me. It works as a laptop when I can’t travel with mine. It allows for internet access when in remote areas. The only issue I am having is talk time and battery power. The main item I am missing is WiFi. So I hope that Att steps up or that I may find a t-mobile account more affordable. I just saw the new blackjack 2 is on it’s way. I hope they fix the issues http://www.samsungmobileusa.com/blackjackII/
