Rhomobile, a provider of open source framework for business mobility applications, has released its new smartphone application framework Rhodes 1.2 with support for using push to enable ‘instantly synchronised data’ on iPhone and BlackBerry devices.

The Rhodes framework uses the iPhone 3.0 SDK Push APIs and the BlackBerry Enterprise Server Push APIs to allow updates of application information to users’ smartphones. The new framework allows developers to utilise their existing HTML tools to create native applications for smartphones including iPhone, BlackBerry, Windows Mobile, Symbian and Android.

Rhomobile claims that the Rhodes framework reduces development costs by enabling developers to code native smartphone applications in HTML instead of in Objective-C or other native device operating system languages. While providing the productivity benefits of web programming, the new framework allows for the development of native mobile apps that use device capabilities such as GPS, PIM data, and camera.

Reportedly, the Rhodes framework also allows users to work with synced local data for access and operations when disconnected or offline.

Recently, Rhomobile has unveiled the compatibility of the Rhodes smartphone development framework with iPhone OS 3.0 and the iPhone 3G S. The Rhodes ‘write once and run on many’ framework allows developers to utilise their HTML skills to create native applications for the new iPhone 3G S – without having to rewrite code for every OS update, the company said.
