    Not sure why this is happening. I have not experienced the same with an original iPhone, the iPhone 3G, and with the iPhone 4 I've been using since last June, but this means your iPhone has a major problem.

    Standard troubleshooting steps in order are:

    Power your iPhone off and on.

    An iPhone reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release. An iPhone reset does not affect and data or settings.

    Restore your iPhone with iTunes from your iPhone's backup.

    Restore your iPhone with iTunes as a new iPhone or not from your iPhone's backup.

    If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, the iPhone includes a one year warranty. Call AppleCare or make an appointment at an Apple store if there is one nearby.

    You may be unaware of the multitasking feature of iOS 4. The phone is like a computer and now has the ability ti run several apps at once. Every time you open an app it will remain running in the background until you close the app in multitasking. Like a computer, if too many programs get running you will notice slower performance and the phone may crash. To access multi tasking from any screen, double click your home button. Your regular screen will move up and fade out and you will now see programs at the bottom. You can navigate the list of programs at the bottom the same way you navigate the hone screen, by flicking left or right. Every program in this list is currently running. To close apps you don't want you place a finger on any icon on the bottom and hold, they will all begin to wiggle. You will see red circles with dashes in the upper left ofthe icons. Pressing that red dash does not delete from your phone, only closes the program. Frequently use multi tasking to close programs you aren't using to improve the performance of the phone and to keep your phone from crashing and shutting down.

    What you were provided with the previous post is not correct or is not accurate.

    The iPhone has always supported multitasking but not with 3rd party apps. The first night with my original iPhone purchased nearly 4 years ago, I was listening to music with the iPhone's iPod while browsing with Safari, sending and receiving email, the same for SMS, and I received and placed several calls.

    That is not a "multitasking list". That is a recently used apps list. All apps in the recently used apps list are not running in the background. Very few 3rd party apps run in the background since there is no reason or benefit for the overwhelming majority of 3rd party apps to run in the background. Regarding removing any of the apps included with the OS from the recently used apps bar or dock, removing the Phone app or the Messages app from the recently used apps bar or dock accomplishes absolutely nothing since both are always running in the background.

    If your iPhone is out of RAM, an app may crash but your iPhone will not power off just as your computer doesn't power off under the same circumstances.

    I don't mean to be rude but your information is also slightly off. The original iPhone does not have the multitasking feature I am speaking of, that is only available in the iPhone 3GS and the 4. Those two phones do continue to run their apps in the background in the multitasking feature accessed by double clicking the home button. Now officially apple tells us that the apps running in the background are in suspended mode and not affecting performance. However, if you call their tech support, one of the first troubleshooting steps they will do us have you clear multitasking for issues such as the phone crashing or low battery life because the apps in multitasking CAN overwhelm the phone.
    To the original poster, I understand this did not resolve your issue so you have a more serious problem. Use iTunes to backup and restore your phone. Backup is as simple as ctrl clicking on the phone's name as it appears on the left side of iTunes and choosing backup. Afterwards, click on your phone and pull up it's summary page and choose restore. When the restore us finished you will be asked to either restore from backup or set up as new. Choose set up as new, which will not load your content to the phone and thus rule it out as an issue, and give your phone a new and unique name so as to protect your backup currently stored under your phone's previous name. If the restore resolves your issue, plug the phone back into the computer, ctrl click, and choose restore from backup to restore your content to the phone. If it does not resolve your issue, contact Apple tech support, your phone will be set up for repair.

    No it is not slightly off.

    Copied from your first post.

    The iPhone has ALWAYS supported multitasking, but not always with 3rd party apps. When you surf the web with Safari while the Mail app checks an email account for new messages in the background and/or while you compose and send new email while listening to music with the iPod, if that isn't multitasking I don't know what is.

    All 3rd party apps are not constantly running in the background after being launched - suspended or otherwise, and all apps in the recently used apps bar or dock are not running in the background - suspended or otherwise. Read the link provided.

    Regardless, powering an iPhone off and on and/or an iPhone reset clears any 3rd party apps from running in the background that were running in the background before doing so. The number of 3rd party apps that run in the background suspended or otherwise are few and far between.

    Does it shut down even when connected to the charger? If not, it may just be the battery.
