well since you are your own network provider...I assume you are a GSM provider operating in the 850/1900/2100 MHz. this is what you need to know to config GPRS
EDGE/GPRS:
Connects to: The Internet
Access Point: wap.voicestream.com <----(this is T-mobile - replace with your AP)
User name: ‘blank’
Password: ‘blank’
Primary DNS: 0.0.0.0 <----replace
Secondary DNS: 0.0.0.0 <-------replace
IP address: ‘blank’ <-------replace if needed
you probably will need to setup proxy also
I hope this helps
