Mobile Patch Utility and Clarification

Hi all,

I want to DLC/patch for mobile devices and started testing from IOS. I am a bit confused about patching and DLC. On the top, due to poor docs, it’s more confusing.

My understanding is that

DLC is downloadable content, where I
released the initial map, and the rest
of the maps will be downloaded by DLC
HTTP content which I will place on the
server by Mobile patching Utility. (to
achieve that I create 2 profiles,
(APP+DLC) one for release with intial
map and other for rest of maps).

Whereas

patching is the process of additional
fixes on the released version of the
game.

My two questions are:

What if I made release 1.0, downloaded maps(DLC), and realised I want to change in Map1 something, lets say want to add an extra cube. Will I have to create DLC or patch? If DLC how and what I need to change in profile? If Patch how and what I need to change in profile? (where are docs)

Let’s say for simplicity, I do not want to use DLC. Just a single release and keep making changes to the same release. I guess I need patches. I am able to create the first patch file (with _P) but on 2nd change, I can not get another patch file. It always creates one single patch for the same release. So how I will have multiple and incremental patch files for the same release? (where are docs)
