PDA WM5/WM6 c# gprs Connection Manager issues

PDA WM5/WM6 c# gprs Connection Manager issues Task is to investigate research some connection issues we are having with gprs and 3g gprs connections from PDA devices. We use wm5 wm6 and wm6pro, htc type pda devices such as 3300 and 3600 with builtin gps. i will supply most of relevant connection code from our current application etc Please only bid on this task if you have experience of this type task. It is a basic requirement that our application stays connected whilst there is some sort of gprs signal. The deliverable will be a program which connects to a fixed ip address and stays connected indefinately... sending a text string every minute, such as date:time string etc It will create a log file with connection related information. Any changes made to code need to be recorded seperately etc More Detail Currently with O2, if the gprs connections fails several times we reset the modem using TAPI functions. Unfortunately when we use this with a Orange 3G connections and some other situations it dosent always work.
