On 3gs with iOS 5.1 I have chosen in the settingspanel the paid option of EUR 0,79 to get rid of the commercial tekstlnes. The menu with my i-tunes id turned up reqeusting my password. I gave that. The 79c option disappeared, so I thought from now on no advertisement. BUT: I still get textbaradvertisements regarding to sms-services. This feels dangerous and not as advertised for what i paid the 79c option. UPDATE: after starting the app again and tapping The 'restore your lost purchases button' the advertisements have gone. So now it works as advertised. The only minor thing is metering spot which cannot ve moved from the side to the center.
