No problem, we were all new sometime
.zip : Any release in a zip is probably a rom or a modification and will most likely be installed with the clockwork mod.
.apk : Any filename which ends in apk is definitely an app and should be installed using a file manager although for security reasons you should always try to get your apps from the official android market first, a lot will have a free version if you want to try before you buy, then the paid version may have the name "Pro" after it.
just when I thought I was getting the hang of all this stuff, I have another question.
this is a different subject, perhaps I should have started a new topic?
while having another look at the fish n chip rom i noticed it as apps2sd in it, I remember (I think after factory reset) it flashed up apps2sd no pation found, while in clockwork mod.
so here are the questions
if I had a sd pation would the rom apps have gone to sd?
I have found that I could add a sd patition in clockwork mod, but what size?
then there is another list to pick from, I assume this is to do with how big the app must be, do I pick 0m?
after this for the apps2sd to work do I re flash the rom?
I have noticed all this TPT stuff as well, but with all the "bricked phone warnings" I decided to leave this alone for the time being.
Sorry for a long winded post. hope you can help
