Latest Good News from Citi ?

After recently ratejacking me to 29.99% and changing to Variable rates and starting to Balance Chase me last month just as I started making larger payments I get this notification in my last statement:

We are changing your account terms. The standard *

* purchase and standard cash advance APRs on your *

* account will no longer increase when the U.S. Prime Rate*

* increases. Effective 02/22/10, these variable APRs *

* change to non-variable APRs as follows: *

* *

* Standard Purchase **APR**: 29.99% *

* Standard Cash Advance **APR**: 24.99% *

At first glance this appears to be a good thing. What would be the point of this – I don’t trust Citi to do ANYTHING in MY Favor.
