My girlfriend has a peculiar problem with her X8 which has surfaced recently: when sending a longer than 160 characters message I occasionally receive the message in a warped form so that the first 160 characters are correct but starting from character 161 onwards the text could be a portion that she never wrote or from a message several weeks, even months old. My phone is Galaxy 3 and I had the same problem when sending messages to her but that seems to have been corrected when I updated to 2.2. Her X8 has had the problem with both 1.6 and 2.1.
