Bad news for Jott users. Jott is out of beta and is converting to a three tier plan. The basic plan is still free (with ads) but the recording time has been reduced to 15 seconds; looks like the ability to Jott to folders (or subjects) which is an idea I blogged about here is still possible but is managed at jott.com.
The good news is there are alternatives. I haven't explored them as yet but you can read about them at Lifehacker's blog. As always, the emphasis is on free.
