3. Phone Credit Flying Out The Window? Turn 'OFF' EDGE
Q: How to turn OFF EDGE?
A1: For non jailbreak iPhones, the easiest way to enable Celular Data Network Column is to use ipcc file @ http://forum.lowyat.net/topic/752226. If you cant see the ipcc file via iTunes, enabled Carrier Bundle Support in iTunes 8.2.
A2: For jailbroken iPhone users, you can download 'SBSettings' via Cydia to disable EDGE. You can also easily toggle On/Off for WiFi, SSH, 3G, etc. Take Note: *SBSettings has no icons. To launch SBSettings, slide your finger at the statusbar where your time/carrier is located. This will launch the program.

Even with SBSettings, EDGE is not completely disable. You need to access the Cellular Data Network column. If you dont see the Cellular Data Network, use the ipcc file from http://forum.lowyat.net/topic/752226 to enable it. If you can't see the ipcc file via iTunes, enabled Carrier Bundle Support in iTunes 8.2.

To disable EDGE, place gibberish words to completely disable EDGE connection like below:
APN: iPhone
Username: iPhone
Password: iPhone

I been using my 3gs for about 2 weeks under Ivalue2, today, i coudlnt get access to 3G (data) error message like "cannot enable data" etc... but it also screwed up my voice plan...ppl couldnt call me...and i could not call out.

Resetting the phone would enable a few sms to come in "6 missed calls" etc etc...but after that cant use phone again.

I had to disable 3G to be able to make voice calls. Anyone experienced this b4? This is very frustrating to me as i need my phone for biz, i didnt even realise my phone was not working till about 2 hours later, when ppl called me on land line

is it payment by maybank debit card accepted ???

Hey guys just wondering how many of u are facing this problem with your iPhone that
sometimes the phone just says No Service until you turn off the phone and on again. Another way is to turn off 3g and signal will be back again. But turn 3g on again and signal goes off.

I'm wondering whether this is my phone's problem or network problem. Maxis doesn't help by telling me to keep my 3g turned off. This problem happened 4 times in the past 3 weeks since I got my phone. Usually happens when I turn on airplane mode at night and turn on the signal again in the morning. But not all the time. Find it really weird.

So just wanna know how many of u have faced this problem. Thanks

same as me.. last time also the same.. u try to erase the sim card using rubber or change a new simcard..

some people say will ok already.. but u have a try lo

Normally, I will just reboot the iPhone..
