*UPDATE* - CarrierIQ is ran through the My Account application from T-Mobile. As noted:
On BlackBerry CIQ is attached to My Account. The Customer will need to accept the permissions to allow CIQ to collect and transmit data.
So as long as you never use the My Account app and never agree to the terms and conditions as well as accept the permissions CIQ will NOT run on your T-Mobile BlackBerry.
While RIM has gone on record to say they do not install the hotly debated CarrierIQ logging tool on their devices while also stating carriers shouldn't either, new information shows that T-Mobile has gone against the grain and does indeed have CarrierIQ installed on three of their in market BlackBerry smartphones.
If you own any of those three devices listed, you do have CarrierIQ installed on them but the claim from T-Mobile is that it is not for nefarious purposes and that personal data is not being tracked. What is tracked however is, battery performance, dropped calls and application failures.
At this time, we're looking into how to possibly remove it from your BlackBerry smartphones but it's not clear if it is as easy as just switching off of a T-Mobile OS onto another. Once we have some more details, we'll be sure to let you all know and hopefully be able to provide you all with a removal guide. In the meantime though, how do you all feel about CarrierIQ being on your BlackBerry?
