I have a Sprint branded Q9c that I installed ArcSoft 5.2.12.45 and set a few settings, it works and it sends/receives. Only thing is the Q9c's backspace exits the arcsoft so if you make any typo's you need to start all over. Is there any program to remap a key as backspace? What I do is use MENU then ADD RECIPIENT and/or ADD PICTURE. I also use the SEND AS MMS on the pictures & videos program, then just add the recipient, works perfect. Wonder if ArcSoft has a patch for this? I use my program to set "x-device-min" (for MetroPCS and "x-mdn" for Boost/Sprint)
