The T-Mobile MyTouch and MyTouch Q (actually made by Huawei) are receiving an OTA update today -- to software version C85B839SP03. Although the phones will stay on Android 2.3.6 for now, there are a few good things in this one. First and foremost, the update allows users to opt out of the Carrier IQ tracking software that is preloaded on the devices. There's a lot of FUD out there about Carrier IQ, but regardless it's good to see that a carrier is letting people have the option to toggle that data collection off. Also in this update is a camera fix, allowing the phones cameras to now realize a full 5MP resolution for photos. Of course as we'd expect, there are a few other random bug fixes involved in the update as well.
