No 3g on my iphone - boo hoo!

[gemmacide]

Hi all, I wonder if anyone can help?
I received my new Jailbroken iphone 3g 8gb today. I synced it up with my itunes 8.2 and everything is fine, except that I cant seem to access the internet via 3g/Edge/GPRS etc. There is just a blue dot in place of where the icon should be.
I called o2 - I am on an o2 pay monthly contract (not the iphone contract but a similar £45 a month one with unlimited web browsing) who gave me updated settings, consisting of changing the info in Settings>General>Network>Cellular Data Network and changing the APN from idata.o2.co.uk to mobile.o2.co.uk, but none of this has helped. Oh, and Enable 3g is set to on!

Can anyone shed any light on how I can fix this? I've scoured the web but cant find anything about jailbroken phones being unable to access 3g or GPRS etc.

Thanks!!

Are you sure there is a data connection in your area to connect to?

Hiya,

Yeah, I have two collegues in the same room who can get online without using wifi on their iphones.

My iphone (2g) started doing that about a month ago, I did some googling and the blue dot is supposed to be a roaming symbol, even though I wasn't. I never figured it out but I was still able to connect via edge though.

A little dot where E/3G goes is not roaming but is GPRS network. Anyways, try unjailbreaking the phone and restoring it to see if that fixes the problem. Maybe there is something wrong with the radio (check the warranty for the serial number to see if there is any AppleCare left).

I agree, the blue dot is the GPRS symbol.

You should be able to access the web via that - though slowly.

Try loading a small page like www.google.com to see if it connects
