Not just that, with the new update every time you launch the iPhone app it asks you "Twitter would like to use your current location, allow, don't allow"
That's interesting. The alert should only be presented to you twice - if you respond No to both cases, it should simply disable location services for the app.
Mind you, I did that manually - at least once I discovered it leaves them enabled the whole time the app's running, which means a significant battery hit on the GPS.
No means no
