Some anonymous Apple insider has dropped top to many famous iPhone/Apple blogs recently regarding iPhone 4.0 OS. Tip states that "Apple will demo iPhone OS 4.0 on March 14th". Well it looks that it's pretty much a rumor, as 14th March is on Sunday and it's highly unlikely that Apple will officially announce their new firmware/OS on a Sunday.
Apple also has recently released iPhone firmware 3.1.3, it didn't brought major changes other than fixing few security issue and bug reported in previous firmware, so release of iPhone firmware 4.0 is anticipated soon but release date has not been announced yet, all announce dates we are hearing are still rumors. As per earlier rumors, OS 4.0 is expected to be released in the last week of March along with shipment of iPad. Next generation iPhone 4G is also expected to be released in June this year at WWDC conference.
