If you know how to update your files, then go to the project android webpage and download the latest file.. unzip it.. delete the zimage and the corresponding htc file in your sd card in your andbot folder and rename the unzipped zimage.xxxx file to just zimage and copy the newly renamed zimage and htcxxxxx (both were unzipped) files to your sdcard in your andbot folder and in call volume should be louder but you wont be able to increase it or decrease it.
So far
AFAIK for me atleast.. mms just works for send not receive
