Have idea for a simple phone app? Why not release it for the 4 big mobile operating systems at the same time: Windows Phone, Android, iOS, Blackberry, symbian, bada, and webOS.
PhoneGap 1.3 was recently released bringing along with it the most useful cross platform development environment to date. The new update mostly is to give Windows Phone 7.5 (Mango) full support of the features. The backbone of PhoneGap is based on web development standards, which innately bridges between the platforms already. The core relies upon Java, HTML5, CSS and many native PhoneGap tools to get the job done. The best part is, PhoneGap is open-source.
Originally developed by the company Nitobi, now part of Adobe, the PhoneGap framework (aka Apache Callback) has seen many contributors add to the project, most notably, RIM, IBM, and Microsoft.
Unfortunately, according to the licensing agreement, PhoneGap can only be used on free apps. However, nothing says developers cannot make money with in-app advertisement. Take a look at the PhoneGap website to get started.
