Swype for the iPad and iPhone is another way to type with a drag motion. Not always the easiest way to type, but some people will love it. It doesn’t interfere with the regular keyboard, so you can use it when and if you want.
To get Swype on your iPhone and/or iPad, download this deb file. If you don’t know how to install a .deb file, probably, the easiest way is the ‘autoinstall’. To do that, check out this tutorial.
Thanks @wyndwarrior for the hard work on this tweak.
