I just heard again today that the "official" beta update sometime this week will include ICS support.
There are two official versions of Swype:
1. preinstalled on your phone through a license agreement the manufacturer makes.
2. the version supplied by the BETA program which your supposed to enroll in to use legitimately.
there is no "paid" version of Swype you can buy.
Swype(now owned by Nuance the company that makes dragon) has in the past taken strong steps against "modified" APK's of Swype and sites that host them. I haven't really seen that this time around(I don't blame AF at all for removing links though better to be safe), but like I said its kind of mute discussion because the official beta is being released any day.
FYI if you haven't signed up for the BETA I recommend you do so!
The latest version is by FAR the best keyboard I've ever used. It offers predication for "tap" typing, dragon dictation built-in, its full of awesome
P.S. I wasn't able to confirm it, but afaik know swype still holds the world for fastest mobile keyboard.
P.S.S. You should use what fits your needs best though
I'm a swype lover, but everyone's different. That's the thing I love about Android you get to customize to your hearts desire !
