I have developed an PhoneGap application using Sencha Touch 2 in Android. Now I want to develop the same in iOS without changing the code. I tried using PhoneGap Build but it was asking for Apple developer registration or developing Xcode using MacBook. Is there any other way that I can generate an .ipa file using Windows XP, PhoneGap?
If your app really is just a straight PhoneGap app -- all HTML, JavaScript, etc. and no custom Objective-C stuff, phonegap.com offers a build service that'll build your app for all the platforms they support. You'll still have to register as an iOS developer and pay you $99 to get a distribution certificate, of course. According to the iOS Build instructions you'll need a Mac to set up your certificate and such. So realistically, you'll need to at least have access to a Mac from time to time, but once you've got everything set up you should be able to use the service to do your builds.
SenchaTouch 2 incorporates directly building native Android and iPhone apps with the (still in beta) SenchaTouch SDK Tools using a Windows, Mac or Linux PC. I am doing this on Windows XP and 7.
After setting up your (paid) developer account with Apple, creating a developer certificate and setting up a PKCS#12 key-store(*) on your PC, you set up a packager.json targeting iOS and use:

To run iOS simulator you need to use Mac OS X
to make the iOS application (which will be output as a folder named build\MyApp.app).
(*) Use Portecle to maintain your key-store.
