I just bought the Z221 and was told that there was software online to use for downloading files to and from the PC... I haven't found any and belive the ATT people lied to me... I used to own a Samsung-Solstice-II-a817 and it has a charger with a diconnectable USB cable. It was the same miniature size as the Z221. I connected it to my PC and it started charging the phone right away. Then it started a wizard to instal drivers. I installed it. Afterwards I could not see it or use it to communicate with the phone. When I plug it in and out it gives me the M/S tones that there is something plugged in, but I cannot see the actual USB device on my computer. I tried using the Samsung PC Studio S/W but it didn't recognize the Z221 ... Since the Z221 is Chinese I hope I don't have to go to some after market Chinese site to download some bootleg software.

I did an I-net search and came up with ... http://webtopicture.com/zte/zte-z221-software.html  ... then it linked me to ... http://adf.ly/9zQjV

I don't trust these sites to I decided to not download the software. As far as I can tell there may be some outhere but I would be taking a risk with my PC and my phone...
