I went to the mall yesterday to look for a samsung i900 battery seeing that it's the same battery that the behold 2 has , so I can have it as a spare .... After being unsuccessful finding one ,I was pissed and ready to leave the mall when i noticed this lil box in a window of a tmobile kiosk . The guy then went on to tell me that they have been recommending it for the last 8 months , to anyone that bought a smartphone .... so I got out my behold 2 and went to tmobile's site and to my surprise , there was no mention of it ,,, called customer care later and asked them about it and they had no idea what I was talking about ... the guy also told me they been selling these like hot cakes .,..,..,..,. WTF !!!!!! T-Mobile ???
