Have you tried restoring it again? Have you tried it on DFU mode?

To get DFU, hold down the home and power button for 10 seconds, the screen will flash at some point. After 10 seconds release the power button but continue to hold the home button. iTunes should then pick up that the phone needs to be restored. There should be NO iTunes and cable picture on the phone screen, it should be blank.

Yeah I've tried all of that several times. I've even tried restoring it as a new phone so it loses all of my settings, but it's still exactly the same. Restarts every 4-5 mins. Of course, it doesn't help that during the whole process it is still restarting itself so it buggers it up anyway.

Ah, bugger

So even whilst restoring it's still shutting down?

lostkat · 27-06-2010, 09:13

Yep. All the time. No matter what I'm doing. It does it whilst it's charging, whilst it's connected to iTunes, whilst it's updating etc.

No.

This is a very interesting read and makes perfect sense.

The important bit:

Quote:

The fix is expected to address a issue in iOS 4 related to radio frequency calibration of the baseband. Readers who saw the original forum discussions say that the issue is believed to occur when switching frequencies; because the lag is allegedly not calibrated correctly, it results in the device reporting "no service" rather than switching to the frequency with the best signal to noise ratio.

iOS 4 introduced some enhancements to how the baseband selects which frequencies to use, so it makes sense that the error may have crept into those changes. Additionally, this explains why iOS 4 has also caused similar problems for iPhone 3GS users.

Additional readers have shared other related experiences that also corroborate the idea that the issue is related to iOS 4's software control of the baseband, including the fact that the issue seems easily reproducible when connecting to a WWAN 3G network but does not appear when connecting to a Microcell 3G. If the problem were simply hardware related issues of the antenna design, it should only affect iPhone 4 units with that new design and should occur at all times, regardless of the tower type. That is not being observed.

You can take that article any way you like, the important part there regarding RF makes sense to me and would explain the problem.

Of course, there will always be the conspiracy theorists who will just say that any software mod will just prevent the phone from displaying 'no signal' no matter what.

What I will say is that I'm getting a stronger signal in my house with my iPhone 4 than I ever did with my 3G and 3GS. I can walk around the house and keep a call going now and I couldn't do that before.

I've said on the OcUK Apple forums that I see this as being blown up out of proportion and I still stand by that.

You can have mine for £350

Kate, my friend just upgraded to a 4, and because her iPhone had 'water damage' (although it's been fixed by apple now & works fine) they won't replace it because they have the record of the w d on file. She doesn't know what to do with it but as I say it works perfectly so she's thinking if ebaying - do you want me to see what she's asking? Won't be the normal price I'm sure.

Blighter · 27-06-2010, 12:26

£350 would be great to get from the insurance policy tbh

They are going (new incl. box/accessories) on eBay for £300, and O2 are paying £230 to buy your old one back.

Ooooh. Now it is the daily fail, but:

The Daily Fail has indeed failed, the Twitter account they are reporting on is a blatant fake.

iPhone 4: Reinventing the way you hold your phone, again.

Just FaceTimed my wife. If you know what I mean.

People who live in houses shouldn't throw glass phones.

To prevent signal problems with the new iPhone, avoid touching the phone at all times.

The unshaven unemployed population is starting to line up at Apple stores. Ugh, go stand outside a FedEx sort facility.
