iPhone cellular data not working? Try resetting your network settings

The problem with this is that it resets one's wi-fi passwords. I have lots of friends whose wi-fi passwords are unnecessarily cryptic (if they can even find them -- lol), and it's taken a while to build up the database of passwords on my phone, so that when I visit, I connect automatically.

Apple needs to split the reset function -- one for 3G tower connectivity, and a separate one for wi-fi.

I found that going into the network settings and turning off 3G and then turning it back on fixes that too (Settings > General > Network > Enable 3G).
Once turning 3G off wait until the status bar turns to EDGE mode (dot appears next to coverage meter) then turn 'Enable 3G' back on.

Also, That Sony ad is really bad.

If you reset your Network Settings and go back to factory defaults, how do your carrier settings get updated? Do you reset your Network Settings and then update your phone via iTunes or is there an OTA update?

I'm leery to do this because 1) a 3G upgrade in my area is imminent and 2) I really only have problems with Call Drops and I don't know if a reset will alleviate that.

Does anybody know if a Network Reset is suggested after the upgrade from Edge to 3G happens?

So no one takes issue with the solution to crappy Touch/iPhone problems constantly being the equivalent of 'backup and restore/start from scratch', or 'erase all your settings'? That's one hell of a device. I still love my iPod touch first gen, but I'm getting sick of having to monkey with the device just to get a wifi connection, or backup and restore to improve sync speed.

If you READ the article you would see these words:

"not only resets your Wi-Fi settings -- resulting in a clean slate with respect to Wi-Fi access points and their passwords"


To TUAW your Sony ads from eyewonder.com are ridiculous, they take over Firefox and render your site useless.

Thanks for the helpful advice! :)

Like WELCHB, I've been experiencing a lot of dropped calls lately, and so I'm hoping this will help, if not resolve, that problem.

I followed your instructions for resetting my iPhone 3G's network settings and they worked perfectly.

Just a minor but quick note: If you reset your iPhone's network settings, your iPhone will shut down after it completes; after you power on your iPhone again, if you were previously connected to Wi-Fi, you will need to go back into Settings to add yourself back to your Wi-Fi connection, as the reset disconnects you from whatever Wi-Fi you were last in.

this used to fix my issue. but my Internet connection issues just get worse. think it's time to hit the bar for a hardware issue on my gs...

If you feel like this is an issue with your phone (ie. you've gotten coverage in those same areas before and something changed, and you're using a current model), call in about it, or if you suspect it may be hardware related, take it to the genius bar. You may want to call Apple first, to see what they think.

If you feel you are in a "drop zone", report it.

(Only do this if you are getting dropped calls in specific areas.)

I am in disbelief - you solved my network connection issues!

Typed from an iPhone that can finally access the 3g network!

Would this help the completely ridiculous amount of dropped calls I've had the last month or so?
