One feature I'd love to see for my OBI110 would be the ability to initiate a callback via an SMS message (could use Gvoice's SMS service).
Other control features would also be nice, but mainly the ability for the Obi to call me back and call the number that was SMS'd to it (from a known number)
A second best would be URL control, but that would require a data plan. This would be useful where one has data but at insufficient speed to handle a call over data.
(if you haven't guessed it already I have unlimited incoming on my mobile)
Thanks! I LOVE my Obi!!!! (I have 2 and have setup many more for family & friends... the Obi is an AMAZING product)
