Lost Mobile Data Connection on IP4

[stohr]

After jailbreaking, among loosing FaceTime and MMS, I now notice that I lost my AT&T Cellular Data. I tried restarting and resetting my network settings. I can't restore because I am not home and I do not use my MacBook for backups/syncing my iPhone. Anyone else have this issue?

Same issue here. I had the connection for a while after the jb but then it just stopped working. Hopefully a fix is found soon!

Well I just added the source to Cydia from the jb your iPhone without losing FaceTime or mms thread and after a reboot sbsettings is now showing a data ip address. I would suggest trying it!

I have no data connection now either. I have 3G showing up with AT&T, but no web pages load anymore. Was working earlier this afternoon, but nothing now...

Same here. I have full bars + 3G but can't connect to anything. Voice still works, though. Tried restarting, removing/reinserting SIM and resetting Network Settings. Ended up restoring it. I'll wait until I hear that there is a fix or that the MMS/FT fix fixes this.

Had the same issue. It fixed itself after a simple restart.

Same issue here on a factory unlocked iPhone 4... had to re-key the APN settings but then everything was fine.

I was having the same problems with full 3G bars showing and calls coming in but no Internet/data connection. If you go into cydia>manage>sources>edit>add and type in http://iphonedelivery.advinux.fr/cydia then click add. Wait for cydia to load the source then click done then click on the source and install the package and your problems should be fixed. This worked for me after I tried resetting network settings, restarts, resprings, removing sim, etc and had no luck with any of them

I jailbroke my phone again and narrowed down the problem to Mobile Substrate. Everytime I install it I lose data, MMS and FT. I uninstall it and everything goes back to normal. Weird.
