Hi Guys, Before getting into programming I had some fun with jailbreaking. The only time I've seen a low memory warning for a serious "non-experimental" version of an app of mine is on the jailbroken device, and now it occurs to me that any of these jb programs could not only be running in the background, but could also consume any amount of memory, and/or leak memory. This should have already been evident because some legit App Store apps didn't launch until I killed some programs to free their memory. So I'm guessing it's generally a no-no to have a jailbroken phone for debugging? It seems so obvious now. My main phone is an iphone 5, and the one in question is a 4S. I don't want to give up the emulators, so I think my best bet is to get an iPhone 4 which is even slower for app debugging. Art.
