If like me, you have been dying to get portrait SMS working on the N900, its time to rejoice. VertSMS by ossipena is still a work in progress, but the first version has hit extras-devel and with that comes the ability to SMS in the portrait mode. If you haven’t enabled extras-testing, here’s how to do it, the usual warning about software from extras-devel applies.
There is no predictive input so far and it lacks notifications as well. Another annoying thing is that the phone’s default virtual keyboard comes up when you hit the ‘Write your message here’ area. But everything said and done, its a great start.
