(Q)How and when should I wipe?
(A)Wiping between ROM flashes is always a good idea, but can sometimes be very inconvenient so her are some general guide lines to follow.
When the android version changes you will always need to do a full wipe and if you change from one type of ROM to another again a full wipe is required. If you are upgrading to the latest version of your current ROM (as long as the android version hasn't changed) you will only need to wipe cache and dalvik cache. See below for some examples.
Moving from CM7 > RunnyMede AIO - Full Wipe Required
Upgrading from RunnyMede v3.0.2 > RunnyMede v3.0.3 - Full Wipe not Required
Upgrading from RunnyMede v2.5.1 > RunnyMede v3.0.3 - Full Wipe Required
Moving from RunnyMede v3.0.4 > RunnyMede v3.0.4 ODEX -Full Wipe Required
