Update: T-Mobile has now removed its original tweet.

According to a tweet from T-Mobile UK’s Twitter account, the previously announced BlackBerry Messenger service will be arriving on both Android and iOS later this month on June 27. A release date for the BBM service, which will arrive for the first time on iOS and Android as a free download, has not officially been announced by BlackBerry, but the tweet from T-Mobile is a pretty good indication on when we will see the service begin to roll out. However, a report from BusinessInsider later claimed that the date is incorrect based on a source close to the situation. We’ll have to wait for official confirmation from BlackBerry to find out for sure, but BlackBerry told us last night it hasn’t yet made an announcement:

BlackBerry first announced the service was coming to iOS and Android at its event last month. The company said that it would be bringing messaging and groups functionality to new platforms first, but also has plans to introduce voice features, screen sharing, and its just announced ”social engagement platform” dubbed ‘Channels’ in future releases.

I talked to BlackBerry PR last night regarding the rumored June 27 BBM iOS date: “we haven’t announced a date.” “No comment on rumors.”
