fixed the issue. Will look into that further Is your program graphically intensive, or does it use features that are only found on specific phones? If not, I would buy the slowest device you wish to be able to support. In that way, it'll run superbly on higher-powered phones. Having said that, the Dell Venue Pro and HTC HD7 are currently being updated to the "NoDo" update (which brings in copy and paste) - so if you want to be able to develop against the latest and greatest, it would seem sensible to buy one of these.
To fix the issue you can do WURLF do a good job of keeping the useragent database up to date. And they have a fallback mechanism so that if a specific version you need isn't in the database, it will fall back to a appropriate match so you still get usable data. This works well when a mobile operator may tweak a user agent by modifying say a build number. However, it was until recently free for use, but (as far as I know) is free for use only on non-commercial projects. You will need to get a license from http://www.scientiamobile.com/ for use on commercial projects.
