Sorry to hear your having issues with the typing delay on your iPhone 4. First of all you may be seeing the delay soley because the iPhone 4 is 3.5 years old. But also doing a clean restore might fix the delay in typing. to. do so go to settings and down the bottom press erase all content and settings. Note you will lose all your stuff but your contacts messages and some app data,
Hope i coluld help

Try reset settings, you will have to input any wifi passwords again but that my help, it seems to have helped others. Aso try holding the power button and home button untill the apple logo appears, let go and let it reboot.

I've had reset all settings fix this issue along with backing up, restoring and bringing the backup back onto the device.

It seems that by putting the backup back on the phone you may be getting the issues back. Next time just restore the phone as new.
