How do i update my iphone 4 to iOS5 without losing apps, contacts etc.?

you can probablly pay to have your service provider to it for you when you go to get your phone that what i did

Do a backup before & then restore from that backup after.

Right click it under devices in iTunes & select Back up.
After the update right click it again & select Restore From Back up

Just make sure everything that's on itunes on your computer is also on the iphone before hand and you won't lose anything.

You can back up your itunes library before hand if it would help you feel better and sync your ipod to itunes before hand......which automatically backs it up or..... you can right click the ipods icon/under devices under and select backup you will find it in the left column . After the update if you wish you can/right click it again and select restore from backup, doubt you'll need to though

when ios 5 comes out tommorow you connect your iphone to the computer and when your device pops up under the devices section there will be a part where it says there is new software available for this device and there will be an update button beside it.

I've been counting down the days for when iOS 5 comes out i'm so excited!!

If you upgrade your iPhone 4 to ios 5, two possibilities may happen ;


1. If you have a jail broken iPhone, You will lose your jailbreak
