Apple iPhone 3G Black Smartphone - Page 7 - Answered Questions & Fixed issues

1) Does your vehicle have an aux input jack (1/8")? If not, then you'll have to do it the old fashion method. Purchase an iPhone cable that uses the RF signal method to play music on your cars stereo by tuning to an specific band and it will work just fine.

You have 3 options. Replace the phone. Pay to have the phone repaired (or do it yourself), or if your phone is jailbroken, you can install Activator, where you can emulate a home button press with another button (such as holding the volume down button for 2 seconds). If your phone is not jailbroken, you will not be able to do that without fixing the home key. In that case, I would suggest a 3rd party repair place, since they will be cheaper than Apple.

Is the phone drained before this happened? If yes, then maybe you should plug it to a wall charger and wait a little longer for it to charge. Also, one possible cause is that it's on dfu mode that's why you can't see anything on the screen. Again, just hold the sleep and home buttons simultaneously until you see the apple logo. If this doesn't work, it's also possible that you got a faulty unit. If it is still under warranty, you might want to bring it to an Apple store to have it checked and replaced if it really is a defective unit.

(Also try changing usb cable, different usb port, reinstall iTunes then restart computer)

You need to open up your iPhone but this depends on your iPhone's model. Almost all models except the first one have screws below them that you can unscrew and open your iPhone. You can check out iFixit.com for a detailed overview of how to properly replace your batteries and to where to buy for a replacement.

It's an indication that the app that you're using is locating your current location. It's a feature of new iOS versions 4.0 and up.

Try to hold your home and power buttons again until you see the Apple logo. I'm assuming you don't have any issues with your home button being unresponsive. If you have that issue/problem before with your home button, try to push it harder for it to work.
Also, try to connect it to your computer and see if your iTunes will detect it too.

power it off then hold the home button then connect to itunes while holding the home button then wait for a message from itunes "itunes has discovered a device in recovery mode it needs to be restored". then just follow the steps to restoring it.

your SIM card has been damaged or you have no service

it is on upper side besides on/off button

There are a number of different physical features that work in unison for the iPhone experience you know. The touchscreen is the main focus of the iPhone frame and where you put all central commands. The power button is up top and can reset things back to the base. Without the Home button, which is the circular button directly below the iPhone's touchscreen, none of these things will be useful. As a physical part of the iPhone that you are in contact with quite a bit there can be a number of problems that you may encounter with the Home button. If your iPhone's Home button begins having problems or becomes unresponsive there are a number of different things you can try.
Blockage
One very common situation is that there is a physical interference to the Home button being read. Irritants and dust can get into the connection port at the bottom of the iPhone and can cause a distraction from the proper purpose of the iPhone. You can try to repair this by taking a clean toothbrush and sticking the bristles into this port. Brush freely so that you can try to get anything that may be up there. Canned air or blowing into this port can also be useful. You may not be able to fix this on your own and instead an Apple Store employee may have to open it up to clean it.
Water
A lot of times you have to look back to what may have happened to it. If you got water anywhere on your iPhone that can likely be your issue. If you have tried most everything else and are convinced that this was water related you can try to dry it out. This can usually be done by just putting it in a warm and dry place and leaving it for quite a while. In extreme cases you can try wrapping it in a towel and baking it in an oven. Do not let the temperature go over 135 or 140 degrees and do this for a few hours. Make sure this is your last ditch effort.
Reset
There are always software solutions for this that include the normal reset functions of the iPhone. If this is the first time this has happened you should try to turn the iPhone off and on and see if this has an effect on the unresponsive iPhone. You can also try to restore it to its factory settings, and this is easily done right from your iTunes account. You can try the restore function at various levels from your settings themselves, but if you have consistent problems with the home button you are going to want to strip everything from your iPhone. If you do this you have to make sure to do a full iPhone back up ahead of time otherwise you may lose contacts, media, or applications.
Apple Store
In this situation Apple can actually be helpful, which is uncharacteristic. Usually a blockage or physical problem can be repaired and often it is a factory defect. Remember, if you are using a protective case this may be to blame for unresponsive iPhone Home buttons. If the solution is not dealt with by purely opening up the iPhone and cleaning it you may have to actually send it back, but if there are signs of physical trauma to the iPhone itself it will likely cancel out any protection over the device through the warranty. This is going to be especially true if there was any water damage.

Try a hard restart, holding the home + lock buttons for ~30 seconds.

Go to Settings->Network-> Cellular Data Settings and enter a valid access point (APN) and make sure to switch on cellular data and 3G

You get the unlock code from this site http://www.onlinegsmunlock.com/ and follow the instructions to unlock and the cost also cheap in this site

Are you using a legitimate ATT sim card or are you jailbroken using Tmobile or some other GSM provider? you can try putting the phone into DFU mode. Have it plugged into the computer. and turn it off. Then hold both the upper sleep/wake button and the bottom Home button for 10 seconds. Then when you get to ten release the top sleep/wake button and continue holding the bottom home button until itunes gives you a message about it recognizing a phone in recovery mode. This should allow you to restore the phone.

connect your iphone to your computer and do a restore

for bluetooth pin numbers the default number is always 0000
if not reset the headset or Bluetooth device and it should be 0000
if the code is still incorrect google the product name and the default code number

upload any mp4 format video under the add file tab in itunes. also you can use apps like Netflix or the itunes app thats preloaded on your iphone. open the app store icon on your iphone to download netflix and other movie apps

hold down the home and power button until you see the plug into itunes symbol. Once that is done start up itunes. then plug you're iphone into your computer via usb. but not until itunes is started. it should prompt you to do a restore.

1) Immediately turn phone off by holding down power button and sliding to off.
2) Use canned air duster to blow water out of all holed in the phone such as headphone port, sim tray hole and the bottom port
3) Place phone in sealed baggie containing silica packs (come with shoes/coats, etc) or uncooked rice for at least 24 hrs.
4) In this time, DO NOT try to power the phone on, this can easily cause a short and ruin a phone that may have otherwise survived.
5) Wait 1 or 2 days and remove from the rice/silica which should have drawn out the water. Now try and power on the phone. I have seen these steps save a soaked iphone more than once.

Good Luck

You want to go to settings, then Wifi. Select your Wifi network that you use for your home computers. Then if you have a password it will ask you to type it in. Once that is done and it connects. go to your homescreen and enter safari.
