Does iPad 3.2.2 OS still have restriction?

I don't know what you mean, does iPad still have restriction?

Please explain.

Do you mean restrictions under general settings?

If you are talking for content and for apps, there are some.

Place and hold your finger on an icon until they begin to wiggle. Then tap the x on the icon(s) you want to delete.
Keep in mind that some icons can't be deleted.

Sounds like a problem on your iPad, and not the software, as no one else has mentioned this problem. Works fine for me on latest iOS.

As stated by the previous poster, this seems to be a problem unique to your iPad. Mine too works fine with the latest OS.
You might consider a trip to the Apple store to see if they have a solution.

Try this:
• Turn the iPad off and on again (hold the sleep/wake button for about 3 seconds until a red slider appears with the label "slide to power off")

• If it din't help, try a hard reset - hold the sleep/wake button and the home button simultaneously for about 6 seconds, until the iPad tunes off. Then turn it on again.

• Go to "Settings - General - Reset" and choose "Reset All Settings"

• If it does not help, restore the firmware with iTunes - IMPORTANT, don't let iTunes use one of your backups… set it up as a new device.
