We just heard from a solid source that RIM is planning on rolling out maintenance releases for both BlackBerry Messenger and BlackBerry App World tomorrow (October 11th). App World v3.0.1 is supposed to include general performance enhancements to application response time with no new features. BlackBerry Messenger v6.0.1 is going to be available for OS 5.0+ devices and includes Social Platform API changes and general performance enhancements with no new features.
When they go live we will let you know along with the full change log. Keep an eye out for them and let us know!
