gprs works only little period of time after restart in qtek8500

[pepsodent]

I have WM5.0 and few programs installed on my qtek8500 (CeleTask, AudioNotes, Oxios, ClearVue). After restart GPRS works for several minutes, then - cannot connect. Did anyone face similar problem?

i get this sometimes on my cingular 3125, and not just with gprs. it does it with mms as well. it happened with winmo5 and winmo6, i just re-did all my settings and it worked for a short period of time. it has now gone back to not working... reboots fix it sometimes but why the hell should i reboot this phone to download a picture....
