iPhone 4 update version 4.3.5 internet tethering gone?

The 'Personal Hotspot' appears in 2 places when u enter Settings on the Main Menu and it appears in General -> Network

Try resetting your network settings if you need to

Have you tried resetting network settings and then switch off your phone and turn back on

If that doesn't work - i would advise to Restore your phone

try hard reset menu and power n see if that works

Don't use Hard Reset because this can lead to future crashes and leaves the system unstable

I kept doing that my previous iphone and it kept crashing

Yea your messages will be deleted - but still be in your backup file - and you can use a 3rd party program like 'SMS Export' to save your messages from the backup

Your photos can be restored - if you have them backed up on your computer

Thats strange, yea restoring is your only viable option

I had the same problem and the solution was to reset the network settings

np 🙂

I just called singtel service and they said that to reset the network setting under general. OS version is 4.3.4.

After reset, Personal Hotspot recover.
