A recent blog post by  Jesse MacFadyen @purplecabbage  discusses an event held by Microsoft to help developers port their PhoneGap based apps to the WIndows Phone platform.  Jesse believes that the effort, overall, went well but mentioned some issues he noticed the developers faced in their porting efforts.   The post is Windows Phone and Cordova/PhoneGap Hackathon  and well worth the read if you plan on moving your HTML/JS/PhoneGap app to the Windows Phone.  He specifically mentions that jQuery Mobile (JQM) is currently the best framework to use to help support multiple phone platforms since these platforms use different browser engines to run your apps.  GeoSyncracy's first app utilizes jQuery and jQuery Mobile frameworks along side PhoneGap.  This really validates the approach taken by GeoSyncracy to develop apps on all the major smartphone platforms with minimal effort on the part of the developer.   I'll push for GeoSyncracy to attend the next event of this kind.
Very Good News! 

Geosyncracy is going to have a booth at Motororcycle Night in Lowell, MA on July 31st, 2012.  
This is going to be a great opportunity to get the word out about the first app, to be released shortly, by 
the company.  It's a fun night for all who attend; You can find out more about it here: MCN Lowell MA

The folks who use to be at Nitobi, bought by Adobe, decided to make the PhoneGap product open source.  This is basically good news for smartphone developers as the product that was known as PhoneGap and now to be referred to as Cordova provides a useful interface to many of the native phone features needed to develop a world class phone application.  

The move to the latest release of Cordova, 1.6.1, proved difficult.  See this thread. In order to work around some flaws in that release it was necessary to move to the latest release candidate, 1.7.0rc1, which worked much better and resolved the issue discussed in the thread above.  I think as developers we just need to give the maintainers of Cordova some time to work out the kinks created when PhoneGap became Cordova.   Of course, that will mean some late nights for us all.

Overall, Cordova makes it easier to attempt to support the many smartphones available today.  It is a nice companion for the developer who is trying to take a Web centric approach in their development of mobile applications as is being done at GeoSyncracy.  (How to move to Cordova (Android) is here.)
