If any more information is uncovered regarding the validity of these claims we will post it immediately.
**UPDATE** This has now been marked as fake on the RussianiPhone.ru site
**CORRECTION** The original poster of this news article mentioned the site iPhoneHellas.gr as a Russian site which is incorrect. It is a Greek site. iPhoneHellas had correctly published information regarding the 2.2 iPhone firmware release.
