Previously I informed you about iPhone OS 3.0 Beta 4 release. In this post, I will be informing you about the Beta 5 release of iPhone OS 3.0. As per the trend the Beta 5 contains bug fixes but that is not all that it contains. Reports say that MMS is a thing in the past and is no longer available. The methods used to enable WiFi are now prevented. Also improvements have been made to the YouTube as well. Now YouTube will stream high quality videos for users using 3G, the same was previously reserved for WiFi users. Last but not the least, ammendments have been made to the StoreKit.To get hold of this latest beta release developers can go to the Developer Center.
