Apple has released a new EFI firmware update for users of the mid-2010 13-inch MacBook Pro, reports MacRumors, enabling Lion Internet Recovery on those machines and allowing them to reinstall Lion from scratch without a recovery disk or USB drive.
About MacBook Pro EFI Firmware Update 2.5
This update enables Lion Recovery from an Internet connection on MacBook Pro (13-inch, Mid 2010) models.

Internet Recovery is most useful when installing a brand new hard drive in your machine, or in case of a catastrophic hard drive failure. The update has yet to appear on Apple’s support downloads sight, but is available for eligible users via Software Update.
Lion Internet Recovery was introduced in the mid-2011 MacBook Air and Mac Mini models last July, alongside the release of OS X Lion. The feature has since been introduced to 2011 MacBook Pro models. It remains to be seen whether Apple will be bringing the feature to other 2010 MacBook Pro models.
