Restore to 3.1.2?

You're not speaking to Apple here - this is a user-to-user forum.

BTW, what are these "major issues" many users are having with 3.1.3 (which was just a very minor bug/security fix release)?

iTunes doesn't allow you to restore to an "old" OS version...

There are some folks that have "said" they have found a way to revert by hacking... of course that voids warranty and is not suggested...

Instead, what issues are you having with 3.1.3 and lets try to resolve them instead of you reverting back to older versions....

Sorry to hijack the thread, but we are also having problems. 3G has become useless at my partner's work. AT&T is going to check the towers. (I'm sure that'll solve the problem).

Turning off 3G and everything works fine. Having 3G on makes the phone useless for messaging, phone calls and any internet activity. We've been through all of the resets to no avail.

So it's either the towers local to you or it still is in fact an OS issue specific to a corruption on the two devices you have...

That said, having the same OS bug on two different devices is quite rare I'll agree so I'm going to tip my scale towards the tower issue...

But when you say all reset steps have been taken...

Hopefully one of those steps was to do a full restore... if this was not done. it needs to be to truly rid the iPhone of an OS bug... but you MUST use "set up as new iPhone" when prompted... NOT restore from back up. If you used restore from back up you need to try the full restore again with "set up as new iPhone"

Check them yourself by putting the phone into test mode.

I have done it that way as the forum has problems with the * key so its a long string of characters before you press Call.

If you get call failed, then you haven't entered the string correctly.

In the top LH corner of the screen you will see the received RF strength in dBm - it should be between 80 and 120. Its where the bars normally sit.

Let us know what it is in your workplace.

Pressing Home returns the phone to normal.

lol Graham nice trick

The number will show as a negative so like -80 or -105...

The closer to 0 the better so -80 is very good signal level and -105 is very bad signal level

Actually -105 is fine as the range will go to -120 and thats bad !

Its a logarithmic scale so the difference between -105 and -120 is massive.

as an added bonus, it is impossible for us to restore to 3.1.2

Going to other firmware is done all the time, many like 3.01. Use Google.

I just recently updated to 3.1.3 also, and would like to restore it back to 3.1.2. I tried google and the things they recommended didn't work for me. Does anybody know how? Thanks!

People cannot tell you here - its against the Terms of Use. Google is your only answer.

It is not meant to be done per Apple TOU policy so reverting would be considered a hack...
