I deleted my emails in my hotmail account from my inbox and deleted folder but there was some important emails that I need to get back now, I know there are ways to retrieve deleted email if they were deleted from a PC or laptop, I deleted them from my iPhone, does anyone know of any way to get these emails back?

Once e-mails from webmail are deleted they are GONE for good. That's it game over.

The real question is WHY, if they where so important, they where in your deleted mail folder!!

Are you using the Hotmail Web client or MS Outlook or another email client residing on your computer?
If you are using the web based client you can try looking at the .html files in your browser cache.
