Iphone doesn t start

If it won't turn on. Meaning it doesn't turn on turn on. The phone is dead and gone.
If the phone turns on but sticks at the apple logo, that means it needs a restore/update.
If the phone turns on and stick at the usb/apple logos. That means it needs to be restored.

To restore or update. You need to use itunes. If the phone is bricked and dead, dead... Then you need to get a new phone

hello,ensure you are not clicking on the key wrongly,i would advice you put the phone off and on back to see if the problem stops.if it doesn't i would also advice you ensure you close any application you are not making use of.it could also be as a result of accumulated opening of applications. if that does not stop the problem,i would suggest you get the phone flashed by a mobile phone authorized repair engineer around you.
wish you good luck,
take care.

If it's under guarantee= go back to where you bought it

wouldn't really know what's wrong with it but try restoring it first

Connect it to your pc with the usb cable
see what happens

if nothing changes try restoring it through iTunes

if it is not recognised immediately: hold power and home button for about 10sec at the same time
your screen should show the cable and a kind of disk

then click restore in iTunes

if this doesn't help= visit an apple store

what you did, is that you restored your iphone just open up itunes, and click restore, and that's it, it will update it to 4.3 version, since it barely came out by apple.

1. Connect your iPhone to iTunes.
2. Hold the Home button and the Power button at the same time for 10 seconds.
3. After exactly 10 seconds, release the Power button but keep holding the Home button for 10 seconds or until iTunes pops up a message saying that it has detected an iPhone in recovery mode. At this point, click OK, then click "Restore" in iTunes.

Turn the iphone off, hold the menu button, now plug in the usb cord that is connected to the computer. Keep holding the menu button until a dock connector appears on the screen. You're now in recovery mode and should be able to restore your iPhone. If that doesn't work you may have a broken logic board. Here is an iPhone Repair Guide that shows how to open an iPhone. Boards are easily available on Ebay. If you want somebody else to do it for you go to iPad Repair

Instead of trying to update when you connect to iTunes you should try to restore the phone completely.

You can find the restore button in the lower right hand corner of your screen. If iTunes asks if you want to update click cancel. You just want to restore.

If it is still not turning on after it reappears in iTunes you should take it to Apple if it is still under warranty they will exchange it for you.

Some users who have recently updated/restored to the new iPhone firmware 3.0 have reported to have got into a problem where their phone randomly doesn’t ring when there is a call nor does the keyboard or slide to unlock button sound anymore. I got into this problem as well after unlocking and jailbreaking my iPhone 3G with firmware 3.0, my iPhone suddenly stopped ringing on calls randomly, resulting in missing a lot of important calls.
So if your iPhone isn’t ringing sound on calls, or if you are unable to hear the keyboard or slide to unlock click sounds, then try the following fixes before you panic and call Apple support:
Fix #1: Push feature is currently not working properly on jailbroken iPhone’s. If you have installed an application which supports Push Notification System then try disabling the Push feature as it may solve the problem.
Fix #2: Try Resetting the iPhone: Settings > General > Reset > Reset All Settings. This will reset your phone’s setting to factory defaults. Your contacts, calendars photos and any other data will stay intact.
Fix #3: There is a slight possibility that your iPhone’s headphone jack may have got some dust or rust which is causing the phone to think that the headphones are still plugged in when they actually aren’t. Try blowing out air in the headphone jack or try plugging the headphones in and out repeatedly. This trick may solve the no sound problem.
Fix #4: Restore/Update you iPhone back and start afresh: If the above solutions doesn’t help in solving your problem then you will have to start from scratch by first restoring your iPhone to the the original firmware
3.0 from iTunes, jailbreak it using redsn0w and then finally unlock(3G users only) it using ultrasn0w. This has fixed my problem.
Fix #5: Install Insomnia from Cydia: Install Insomnia as your last resort. When you press the power button on the top, iPhone goes into sleep mode after 30 seconds, in the process turning off your WiFi, sound and other stuff. When Insomnia app (available for free from Cydia) is enabled, applications will keep running and sound & WiFi will stay connected when the screen is off. This should fix your problem if all of the above solutions have failed to fix it.

Apple will be able to help, they can find a way without restoring your entire phone, you can call apple at 1-800-MY-APPLE.
