For my app for iPad I need numeric keypad for numeric input fields like numpad in Phone app in iPhone (http://db.tt/Y9O9X80B). Could you add it to the jQ Mobile core?

Sorry, but this isn't remotely on our roadmap and we can't take donations earmarked towards any specific activities or deliverables. It would be pretty straightforward to find a developer capable of making this as a custom control.
