A little sneak peak at the mobile version of HelpSpot coming in the next release. There's so many compromises when doing a mobile version and I expect to have to make adjustments over time, but for the first rev of it I'm keeping it simple. Just basic functionality and keeping it optimized for small cellphone screens. If I find more people are interested in PDA use I could perhaps change things a bit to take advantage of the increased space, but for now keeping it small will work well on PDA's and phones.
