I had this issue on my iPhone, where I bought several apps, one in particular I really liked called BeatMaker (wish multi-tap was possible on Android 2.0.. I'd be working on a similar app for Android if we could hit several keys at once!!). When I gave my iPhone to my sister-in-law, she was not allowed to keep those apps.. that is to say, changing accounts required a phone reset, clearing everything. I then asked if I could move those apps to my wife's iPhone.. same account as me, we got 5 phones on that account. I was told nope.. they were tied to the device and acct. Whether this is a mistake or not.. is the same issue present on Android phones? I mean.. if I decide to upgrade to a better phone in a year, can I move my paid for apps to it? What about if I lose this phone and replace it.. or what if I get my wife on my verizon plan, and want to give her an app instead that I paid for.. is that possible? I am unclear as to the "rules" of paid for apps, especially bought thru the store.
