Blackberry OS 4.5 Not Officially Arriving Until September

The Blackberry Internet Services 2.5 upgrade (and subsequent downtime) is still go for a June 29 launch, but there's a catch. According to the Boy Genius Report, some of the "sexiest" 2.5 features won't be available until Blackberry OS 4.5 arrives-in September. From the looks of the BIS 2.5 presentation they got their boy-sized mitts on, at least one of those features is push AOL email and Hotmail/MSN accounts. Of course, if you have a newer Blackberry handset, or plan on buying one before September, it will come with 4.5 OS already installed. [Boy Genius Report]
