If you're an iPhone or even an Android-phone owner hoping to get in on some of that Firefox Mobile Alpha lovin', I've got some bad news: it's unlikely to transition to those platforms any time soon.

In an interview with SiliconRepublic.com, Mozilla's director of mobile engineering Christian Sejersen has stated that development for the iPhone is certainly not going to happen due to two restrictions Apple places on developers: firstly, that you can't write an application which duplicates built-in functionality as Firefox Mobile would for Safari; and secondly that you cannot run background processes on an iPhone.
