Install it like a normal app and then enable swype in settings>locale&text
I made a new version of the app that should fix a few of the slowdowns it has. Download it over at iq0. In order to have 0 crashes in the new one, you have to disable sounds. Then you can do whatever you want.
It should also work for everyone now! No more install error!
The OFFICIAL leaked update is on my site now. Same link as above ^^. It should work 100% for everyone, but I haven't tested it. If it won't install for you, uninstall the old one. Thanks Zappletoo
Update #3 OFFICIAL beta Link to the site in the post.
