Hi, I am experiencing the same issue.
I have a text field set to read only, which is populated with data entered & saved from another page.
However, when using my app on my Sony Xperia AcroS, the text field when touched brings up the keyboard.
It allows data to be keyed, but does not overwrite it.
Also, it does not do this for all the text fields, only some.
I am using the latest version of MobiOne
