I am creating an cloud based messaging app using Phonegap and HTML5. So far I have developed the main functionality of the app and now I need a kick ass UI. I have hand drawn/described 9 screens which I have scanned and attached to explain the screens that I need created. Now here is where it gets interesting, I want to have a design for each of the following platforms iPhone, Blackberry and a generic mobile device (for android and Windows phone). I want them to maintain a consistent look and feel but have the respective subtle platform specific UI features such as the ubiquitous back button on the header for iphone which would not be required on the generic mobile device as these usually have a hardware back button. So in essence, there will be at least 3 sets of deliverables, one for each platform. If my hand drawn diagrams are not clear please ask. NOTE The screens provided are meant to guide on the required functionality, I would love to see designs that are creative yet simple without conforming to rigidly to the structure in the wireframes provided. If you think there is a better way to implement some screens or flows, show and in your submission and explain very briefly why, I am really just looking for creativity and simplicity. I will expect PSDs in the first instance and when I make my selection, then you can proceed to make the html, however, if anyone feels they are better off jumping straight to the html, that's fine by me. I do not expect any javascript programming to be done, just simple html5 and css. Let me know if you have questions. Good luck and may the odds forever be in your favour!
