I made notes of the app versions while under 1.1.3 and now that ive updated to 1.3.1 I noticed that both the clock and phone apps have gone back in version numbers.

1.1.3 versions
Clock 1.1
Help 1.0.21
Phone 1.1
All others at 1.0

1.3.1 versions
Clock 1.0
Help 1.2
Phone 1.0
All others at 1.0

Bit strange, aint it?
