Which SMS app do you use?

I use the default one. I noticed Handcent likes to lock my phone up sometimes, forcing me to pull my battery.

 

i used to use handsent and i really like it for the custom things you can do but i uninstalled it and right away my mytouch ran alot smoother with no keybord lag. i just use the default now with the sms popup app. everything runs smooth
i also used to have issues downloading picture texts with handcent. none with the default however.

 

been using handcent the second i activated the phone and i love it.

it sometimes force closes but usually when the popup feature comes on.

 

definitely handcent. i used chomp, but it does't have the wonderful quick options in the sms popup like delete, add to contacts etc.
