I'm trying to set my EDGE info for T-Mobile, and in Settings -> General -> Network -> EDGE, i start typing in a field (APN in this case, but i've tested typing in the other fields before) and switch focus to a new field, the app crashes (i'm thrown to the Home screen). If I just push back, it hangs for a bit and I can't go back or tap any option on Network.

This is preventing me from entering EDGE info. Anyone else having this problem? I've reset it a couple of times, and killed some processes too to see if something's mucking around preventing that info being saved, though it seems more an UI bug.

If not, where's that data saved? Is it saved in /System/Library/PreferenceBundles/EDGESettings.bundle/EDGE Settings.plist ?

Well I didn't find the root of the cause, but I found a workaround.

The EDGE information is stored in /private/var/root/Library/Preferences/SystemConfiguration/preferences.plist . This is an xml plist so it's easy to edit. Copy it to your system via scp. I'd also make a backup. Edit the section:

Code:

			<key>apn</key>
			<string>wap.cingular</string>
			<key>password</key>
			<string>CINGULAR1</string>
			<key>username</key>
			<string>WAP@CINGULARGPRS.COM</string>

There's 2 apn/password/username sections, this is the first. The other one looks like it has to do with visual voicemail.

Replace this with your own network's settings. For me, using T-Mobile Internet in the US:

Code:

			<key>apn</key>
			<string>internet2.voicestream.com</string>
			<key>password</key>
			<string></string>
			<key>username</key>
			<string></string>

then copy it back over. Reboot the phone, and it'll work.
