Orange UK 4.1.1.4 and the 4.2.1.1 release

[Guest tsutton]

My C500 phone's version is 4.1.1.4.

If I upgraded to the latest UK version which is 4.2.1.1 and if for any reason I didn't like it or any programs doesn't work, will I be able to run the RUU_v0.995_OrangeUK_v4.1.1.4.exe file again to downgrade?

Or should I do something in order for the downgrade to work?

Many thanks,

No one knows the answer? :)
