Swype flashing on and off
As per @Chahk's answer


  I guess it depends if Swype came pre installed on your handset. In that case I don't think you can uninstall it. In either case, try going to Settings -> Apps and see if Swype is listed. Tap it and try to uninstall it. Then you can go to beta.swype.com, download the installer, install it, run it, and follow directions to sign in and install the beta.
