LUBBOCK, TEXAS -- The location for the adapter to charge the unit is located on the side of the phone near the bottom. Right where a person holds the phone.
Also to sit it in a holder of the clamping type is not going to work.
Another problem is the only adapter available for is the clip in type which is very week design wise,and sitting out the side as it does, makes the cords weight to start pulling out. The poke in type are better but coming out of the bottom of the unit. I love the fact katana has no external antenna to pull up,as those I found to be inadequate. Also love the screen size,but find I have no control as to the font size at world poker tour Texas hold 'ems game site. The 3100 series had a larger phone and I could see the opponents name and money as well as their amount of a bet. All I ask is to please consider seriously about the location of the port for charging and the type is limited to only the clip in and not the barrel shaped poke in kind of chargers.
GREENWOOD LAKE, NEW YORK -- I have just purchased this cell phone from Nextel. The way it's designed when you press in the walkie talkie button with your thumb your other fingers hit the other side of the phone where the private button is... So you try to talk & it goes into private!!!!
