my curve is very acting odd
 

its slow. and i notice it alot with my texts. it takes forever to send. sometimes even after iv hit send ill come back later it the text wont have sent.
but my main question is: how do i make it faster?

If this is happening on one contact more so than others, open a message from that contact, select reply, press the menu key, and select remove history.

See if that clears it up.

If the above doesn't work, try a battery pull.

How much free memory do you have?

Do you have good coverage?`
