Android :: Frameworks Similar To Firefox - JQuery - Templates And Data Linking On IPhone

We have a great software foundation based on Microsoft MVC 2, Entity Framework 4, Repositories, POCOs, Service and Control layers, C# Views, JQuery and html. Firefox pulls 100 records in 250 ms, drops it in to a template, links the data to the markup, and we sit back and drink margaritas.

Boss walks in and says he wants an iPhone app. I bet we need an Android app too.

What frameworks could we use to easily jump from our Microsoft comfort zone in to the wide, wide world of the Apple iPhone / iPad, along with a follow-up Android baby.

I imagine we could use our JSON controller methods to communicate. Is there some type of a client side JavaScript consuming app framework we could get a reasonable Website like interface re-working? They didn't like the idea of simply running the whole thing in Safari, which works pretty well.

Needs:

Send and receive JSON objects
Some type of template engine so we can pair up objects to markup, or at least some way to separate design from programming
Something similar to JQuery would be nice
A good editor with auto-complete and highlighting, something that compares to VS2010

It took us two years to incorporate design patterns, Agile methods, and Domain Driven concepts using MVC and Javascript. We may have two or three months to re-produce the same functions.
