Connection Manager setup

Hello all
i posted this question in microsoft.public.pocketpc.developer and i got
little help
then i found this group which seems like the wireless group
i have a small application that uses WinInet to download files from a
web server
the application works fine when the phone is cradled/on the emulator
(WM 5.0 SP/PPC)
when the deploy the application to the phone and its not cradled, i
don't seem to have an Internet connection unless i have Internet
Explorer running in the background :-(
I do have a data plan on my GSM phone, i can access my email/the web
etc.
if i close IE my app can't access the server no more and InternetOpen
will succeed while InternetOpenUrl will fail.
i have the following code to establish connection to the connection
manager, the call to ConnMgrEstablishConnectionSync() fails all the
time so i used
ConnMgrEstablishConnection() instead which succeeds on both cases
(phone cradled and not cradled)
Regards
Mo
