Here are some of the problems you may have encountered:
- No 3G or Edge
- Can’t connect to wifi
- Problems with YouTube
- No push notifications
There are 2 possible solutions for this.
The first fix is to reset your network settings. On your iPhone, go to Settings > General > Reset > Reset Network Settings. After resetting your settings, make sure to reboot your iPhone. It is very important to reboot or else, the changes won’t take effect.
A few people told me on Twitter that this didn’t work but resetting ALL the settings then rebooting did work. So try this if the first fix didn’t work.
The second fix is pretty simple too but it does require you to have an Internet connection. From your iPhone, go to Cydia and add this new source http://cydia.iphoneil.net.
After adding this source, search for an app called Push Fix and install it. Reboot your iPhone and you should be good to go.
If the problems persist, I suggest taking more drastic measures by restoring your iPhone. I know, I know, restoring is not fun but it’s always a good thing to do when nothing else works.
If you choose to restore your iPhone, make sure you set it up as a new phone. Do not “restore from backup” as this would bring back some of the bad settings that caused your issues in the first place.
If you tried all of these fixes and you’re still experiencing issues, then I’m not sure what else to tell you.
