My Regwireless webviewer 4.0, emailviewer or any of those 3rd party IM+WAP etc do not work even when i had OS4.0 and TCP configured as 'internet' for the APN as suggested above. Mine is Singtel from Singapore and even the Singtel boys are still scratching their heads as to why it didnt work. they've downloaded the Reqwireless to configure on their sets but it aint working too.. any one can help? maybe is the confusion of using WAP gateway APN etc... many thanks
