Thank you for your response.
Well I am not an expert but I have done some VS 6.0 C++/VB programming and work with php and perl programmers. I also work for the largest wireless firm here in the states - however in IT, not the cellular part. I may have access to some pretty good resources. I have a qualcomm (cdma - BREW) development kit. With that software and a serial port sniffer I have managed to capture the serial port communication from my vx4500 while it is pulling the ENTIRE file system out of it's memory. This includes phonebook, call logs, in/out sms messages, wallpaper, voice memos, ringtones - everything. The send seems to be all binary but the data coming back seem to be mostly ascii. The only thing missing is notification from the phone when some event occurs such as an incoming call/sms etc. There may be a pin on the connector that goes logic high during an event like that. If you desire to move forward I would be willing to devote some time to helping you with equipment/logs/asking questions around this office etc. You have made such a great software. It would be shame to not make the support wider don't you agree? If it supports CDMA verizon phones better, I'd buy it!
BTW, I KNOW that LG phones can send battery and signal level info through the serial port. I have seen it on our "Smith Micro mobile office software."
