Could you please elaborate what is the "battery status today" that you use for mToday with minimal memory?
I try to do the same: one mToday profile with the applications I commonly use and the other mToday profile for iGO8. The profile with commonly used applications works OK but when the link of the empty profile for iGO8 is invoked it stuck my HTC Trinity such that it needs a hard reset. The succeeding boot yields the empty Today.
Not a convenient way to switch profiles, though...
