IPhone touch response slow since update

Question

Since updating, I've noticed the touch response on my iPhone has really lagged. For example, I touch SMS and it takes a couple seconds to respond. When I'm typing a text, again, it takes quite a bit longer for the iPhone to recognize the touched key. (This response lag happens throughout the iPhone, not just texting. That's merely an example.)
Is this an update issue? Is anyone else experiencing this?

Answer 1

I agree also, the phone is MUCH SLOWER, especially with typing and text.. please send feedback to apple at:

Here are my issues, from the email I wrote in the apple feedback:
My issue is with the keyboard typing and texting functions. I have three areas that have SIGNIFICANTLY affected my regular ease of use and efficiency while typing.
1. Keyboard typing is SLOWER! The keyboard typing response no longer keeps up with my fingers, and continually mispells words because the time between typing and places the letter on the scream has SIGNIFICANTLY DECREASED. Whether it's becuase the typing features were changed with the software, or the unit is diverting processing to other areas, the typing take 30% longer than before the 2.0 update.
2. Word recognition and replacement is COMPLETELY DIFFERENT! Before the update, the phone would learn words I used often, and they would appear as I typed making it easier and faster to write a message or email. Now the phone doesnt remember the words I used to use, AND it doesnt learn them!! It also gets ordinary words wrong, and replaces them with obscure words that don't fit, unlike the earlier software edition which was way more convenient and efficient!!!
3. Sending a new text to someone, with an old string of messages from the same person already existing in the inbox. In the previous software, if you sent a new message to someone, and an old string was already in the inbox, the new message would send and then get placed right under the old string and it would show you after it sent. The computer would recognize it sent to the same person and just add it. With the new version, it's almost as if the software went backwards, and is SERIOUSLY decreasing efficiency..
For the new version, after you send a message and the person already exists in an old string in the inbox, and new message box will appear after sending with JUST the single text sent. After hitting the 'Messages' button and going back to the inbox, you will see the persons name and a string for them. Clicking back onto the message, it will bring you to the TOP of the OLD STRING, with the new message sitting at the bottom. The programming for this DEFINITELY changed, with the new command bringing the message to the top, instead of the BOTTOM of the message, AND it doesnt look for old strings after being sent, waiting till later to be added together. This seriously takes away from its function. PLEASE CHANGE IT BACK!!!
