Q: iOS 6.0.1 problems with my iPhone 4s

try resetting all settings.

Settings>general>reset>reset all setttings this generally fixes software glitches

Also restarting your phone daily and making sure you close out your applications using the multitasker will help prevent problems such as these.

if resetting all settings is not satisfactory to you, your next option is to restore the phone as new, and sync your apps back over.

Not enough information is present in order for us to be able to help you. We will need specific applications you are using (causing the problem), what services these applications require (data connection, etc), what service you are using (etc).

so the apps are crashing after you've done restore as new? the phone itself may need service then. set up an appointment with your local apple retail store, or call applecare

The words you using are familiar, you copied my post? But anyway, no people reply my message in other post thanks to you someone is helping on this issue although the problem is not fix yet, hope Apple may fix this issue on the next update. Really annoyed by this, it feels like your phone memory is not enough to support the apps you're using.
