The problem is, I have no idea how to use them. I can't find anything related to this kind of extractor on the web. I think you are meant to hit a hammer on the top of it, but it doesnt seem to do anything.

I repair a lot of iPhones , ipads, but sometimes when i have to change a battery there's a sort of smell like polish remover coming from the battery .

The odour is not very annoying but when i sniff/breathe this odour, I feel a few headaches during 1 hour or less.

This odour can also be breathed sometimes on new batteries (Which are defective) or used batteries and sometimes also when taking off the batteries when it is broken

What this smell is composed of ?

Thanks

I know the free ones normally have lots of mistakes in them so don't mind paying for the files, just don't know where to source them from?

Thank you in advance.

I just bought a second hand iphone 4. The previous ownner informed me that he had bought the iphone from an Apple store from UK and for two years he used it in Cyprus with a local network carrier (he told me the iphone isn't locked). After he bought a new phone he shut down the iphone for one and a half year since today that i bought it.

After inserting my sim card I get a message saying " The SIM card is from a carrier that is not supported under the activation policy that is currently assigned by the activation server" and therfore I cannot activate the phone. The crazy is that I am using the same carrier as the last owner...

Any advise?

I have also try to activate it through itunes (I am getting the same message), I did also a hard reset but nothing.

I cleaned everything out, made sure I was being very careful, using all the proper tools (utilizing my brand new iFixit Pro Tech Toolkit), etc. I got everything back together, then powered the iPhone on.

The good news: the power button worked!

The (very) bad news: about 5 seconds into the boot process (showing the Apple logo), the screen dims and some text appears, as if it were booting in verbose mode. Here's the text:

[NAND] _FindFlashMediaAndKeepout:601 physical nand block offset 1

[NAND] start:356 this 0xa3148400 PROVIDER=0xa16f5e80 flashMedia=0xa16f5e80

Please help! I really hope this is fixable. From my (minimally educated) look at what I wrote above, it seems like the problem is either the unclean shutdown or physical memory. *panicking* Thank you in advance for your help!!!

The mute switch isn't on, I've switched it back and forth. I've tried plugging and unplugging headphones into the headphone jack numerous times to see if some debris is in there. Nothing. I've tried cleaning the headphone jack with a cut Q-tip and a little bit of electronics cleaner, still nothing—though the first spin of the Q-tip looked pretty dirty since I've never cleaned it before. (The iPhone is about 1 year old.)

The iPhone 4 will play via headset, Bluetooth, dock connector and via the earpiece for phone calls.

And the weirdest part is that the iPhone 4 speaker WILL playback normally through the speaker when running Voice Memos, Skype or Talkatone apps. And if I move the ringer slider in Sounds prefs it works normally and produces the different levels of ringtones.

The iPhone 4 will also produce keyclicks if I remote-lock the phone via iCloud and press the passcode, which has the keyclick sounds.

Alerts through the speaker don't work for SMS or TextFree. Keyclicks don't normally work via TextFree—but for some reason it worked normally once and even got an SMS alert through the speaker. But after going to Music.app volume control, it disappeared again.

Weird workaround

If I have both Skype and Apple music app going, make a Skype call, put it into speakerphone mode (sounds comes out of the speaker), open the App Dock, switch to Apple Music app and hit play, the volume control remains up and works normally (though the audio is playing over the Skype call's audio).

I'm running an iPhone 4/32GB iOS 5.0.1 on an unbroken iPhone. I've already done a full a restore three times. One of those times I remote-wiped the phone and restored.

UPDATE 12/16/11

Ran it without loading backup after yet another restore (actually two restores) and there are no sounds from the device, which was plain without loading any extra apps onto it. No keyclicks. Once, after a restore, it made the 'hey I'm plugged into power' chirp, but that was it. Of course, after full restore from backup, sound still has the same weird problem as above.

Yes, the Phone app works via speakerphone, and I can control the volume. And like Skype, once this audio channel is open, the Music app can play through the speaker—but as soon as the phone call hangs up, the audio from the speaker for Music app is gone, just like my test with Skype.

It seems like a programming call is routing audio in different ways in the iPhone 4. The app Recorder does not play via the speaker, but maybe it uses the music programming call to go through the speaker instead of the voice one.

The phone is out of warranty, as it was bought a year and a few months ago.

Could this really be a bad headphone jack causing all of this?

I have dropped my iPhone 4 last week from my pocket.

The problem is, since that happened, the back section of the iPhone, heats up and gets very hot. The heat is on the right side of the phone (where the rear camera is).

This results in the battery draining VERY fast. With just some casual safari browsing, the battery falls by about 10% - in just 2-3 minutes.

When charging the phone is EXTREMELY hot.

The rear camera, also suffered a shock, and the focus motor does not function any more.

The exterior of the phone stayed perfectly fine, but I fear that there is some sort of short circuiting within the board. (cannot be the battery, as it does not get hot).

Does any body have any idea how to check for short circuiting within the board?

If you have any suggestions please help!

many thanks

iPhone 3G loses signal randomly and for no obvious reason, everything else works just fine.

• Until a few days ago the phone has never been dropped. Then it was dropped from about 1 meter, twice...
• The phone is just over 1 year old

• Waiting
  • Nothing..
• Rebooting
  • Brings service back for a while
• Activating and deactivating flight mode
  • Brings service back for a while
• Re-seating sim-card
  • Brought back service initially, but didn't solve problem

1. Loose cable?
   • I don't see how that fits in. I mean, re-booting gets the service back. If it was a loose cable it shouldn't help to re-boot..
2. ??
3. My observations indicate that the phone is only ever on 3G network. Could the problem be in or around the UMTS chip?
   • Considering logic board replacement or contacting someone doing BGA soldering.

Yesterday I changed the whole dock assembly to see if that could fix the problem.

Today it lost connection again. So it didn't work.

Now I'm considering to get a new iPhone or doing a logicboard replacement on this one.. Also I could find someone local that does BGA soldering and ask them to find the chip that has to be loose on the logicboard...

Either that or I'll decide that I can't afford it because I just bought an iPad....

I also added a third theory.

Either way, thanks again for all your help and comments!
