My ipnone 3gs has become very noticeably slow to open apps, even switching into a new email from the notifications menu takes around 2 seconds.

Originally, this would take much less. Closing all apps to alleviate memory has no effect to the better. There's enough free disk space (3GB free).

Browser data cleaned. Any other form of clutter I should remove?


What could be the cause?

Anything that can be done to solve this? it is really a productivity bummer.




iPhone 3GS, iOS 6.1.3

    Hello Matan3242,


    Welcome to the Apple Support Communities!

    I found this article while researching the symtpoms you state here named iPhone: Troubleshooting a cellular data connection foundhttp://support.apple.com/kb/ts3780.

    1. Toggle airplane mode: Tap Settings, turn airplane mode on, wait three seconds, and then turn off again.
    2. Restart your iPhone.
    3. Ensure that your software is up to date:
    4. Remove the SIM Card and reinsert it. Allow the iPhone to acquire the network again.
    5. If your SIM card has SIM PIN enabled, try toggling it off: TapSettings > Phone > SIM PIN.
    6. Try another location. If a different location works, but the original location still does not, contact your carrierto report the issue.
    7. Reset network settings: Tap Settings > General > Reset > Reset Network Settings.
    8. Restore the iPhone as new.
    9. Contact your carrier to:
      • Verify that the iPhone is properly set up on the account with the appropriate, current data plan.
      • Verify that there are no account-related blocks.
      • Find out if there are specific error messages in the carrier logs that could help determine why the issue is occurring.

    If none of the above steps resolves the issue, contact your carrier, make an appointment at an Apple Retail Store, or contact AppleCare to troubleshoot further.


    I know you have reseated and replaced the SIM card already so you can skip that part.

    One thing to take into consideration would be your wireless carrier, depending on the carrier, if it has gained many customer in your area, or in general, this would cause more of the bandwidth to be soaked up, causeing everyones speed to be reduced.

    Try a reset on your iPhone (nothing will be lost).

    Press & hold both Home & Power untill you see the Apple logo (about 10 seconds).

    Ignore the power off slider.
