When T-Mobile first released the BlackBerry Bold 9900 we knew it would eventually get WiFi calling support. Al Sacco from CIO has received further clarification when we’ll see this.

From T-Mobile PR representative Kevin Wren:

  • A maintenance release from RIM is expected for the T-Mobile BlackBerry Bold 9900 in November 2011. That update will include Wi-Fi Calling functionality
  • With the update, the Bold 9900 will have Wi-Fi Calling performance and benefits similar to T-Mobile’s other Wi-Fi Calling-enabled BlackBerry devices.
There’s no specific date in November, but at least there is a more concise time-frame. Al also noted that he has “heard rumblings that calls initiated on cellular networks won’t seamlessly “hand over” calls to Wi-Fi, or vice versa.”
