The latest version of iOS, version 5.1, was released in the week commencing 5 March 2012. Will test it to see if there are any glitches with iStayHealthy. I am not expecting any glitches. But one change I know I have to implement regards image resolution. As many of you will already know: the display resolution has doubled. From formerly 480x320 pixels for the iPhone to 960x640 pixels (a pixel is a picture element - or dot on the screen). Given that, plus the fact there is a small change re the name of one drug (Complera), a new maintenance release for iStayHealthy iPhone is due.
