Hi! I'm just wondering due to new personal project which is the limit (in MB or GB) of documents directory of my app. I just wanna save a lot of photos, so, has documents directory a limit for archiving downloaded photos?

Hi, I have an mobile web application that I'd like users to be able to use on "home screen mode" (that is, adding it as a bookmark to the homescreen, and then launching the web app via the home screen button).

I like to keep a store-bought version of my iPhone apps on my phone so that I can reproduce any customer issues that come up, but I obviously also want to run the most current development version. I can install both (one from iTunes, one from xCode) but I'm interested in ways that I'm better able to tell the two apart. I could just chang...
