I tried it a while back. I asked for a refund from Handango and got it. Couple things wrong right off the bat. The Manual is written entirely for Windows, Palm, Symbian. There isn't a screen shot or anything else BlackBerry in it.
The mForm designer that is supposed to come with the enterprise edition simply does not exist at all. I traded emails with the publisher over this point and they finally admitted this to me, yet at the time I purchased this from Handango, their text clearly stated that the Form Designer was part of the package. It isn't because it's not compatible with the BlackBerry.
In the short time I had the software I found it to be difficult. I really wanted the form designer so I could make custom databased applications, and what I saw was nothing more than just seeing raw fields because that's as far as the application has been ported.
If there is a 30 day demo, try it that way, but if you want the form designer, seriously call the company as I did, because no matter what you read on their web site, it's wrong. There is NO form designer for the BlackBerry.
Get a copy of the manual FIRST so you understand what it is you're actually buying. Personally, I told Handango it ought to be pulled from the store.
