Tip for those with lagging SMS keyboard

Mine has been lagging like crazy, even after the 2.0.1 update. Something I found that works for me is as follows:

Type one letter into the message field, lets say the letter 'A', then move your cursor in front of that letter 'A' that you just typed.

After moving your cursor, proceed to type your entire message and erase the letter 'A' when you are done with your text.

By doing this process, I have ZERO lag in the keyboard.

Give it a try.
