It’s been two weeks my iPhone 4 acting like a bitch. Always trying so hard to find Indosat network, after 30 minutes it end up with no service status.
I’ve tried to restore, set up new device, even jailbreak but no result.
Today, I searching in official Apple forum and find something useful. If you having similar problems, try this:
- Go to Settings then Reset All Network Setting
- Do hard reset by holding power and home button at the same time, hold until your iPhone restart
- Turn off wifi, data, push notification, or wifi. Use them only when you need it.
