The new mobile beta requires Act 12 SP1. However, when one goes to Act/About as instructed, the version number is listed as 12.0 or 12.1, and there is no indication if either of these is SP1. (12.1 is, as it happens). If Sage wants you to check if you have SP1, it should say "SP1" at the spot where one is instructed to look. Otherwise Sage should instruct the user to look for "12.1". By the way, I couldn't find anywhere in Act's documention any information on what version number corresponded with the Service Pack.
