I have a 1st generation iPhone with a prepaid Globe SIM running version 2.2.1 firmware. When navigating to Settings -> General -> Network -> Cellular Data Network, I have below the settings configured on my iPhone:
Regarding these settings, I have 2 questions:
1. When I connect to Globe's mobile network using the above settings, do I use EDGE or GPRS?
2. I read on Globe's iPhone site that all I needed to connect to their mobile network was to configure the APN. As such, can I omit the username and password or are these both necessary to connect to the internet?
