My iPhone 2G (original) is really showing its age. It is super slow, and can't even compete with the new iOS4 devices. It can't even run iOS4. So, I want to upgrade to an iPhone 4. My mom says that it is "extravagant" to upgrade. I don't use a lot of data, so the $15 data plan would suffice. I have the $20 unlimited data plan on my iPhone 2G, and use about 75MB of that per month. My mom says that if I need to upgrade, I have to get a cheap $50 phone from the AT&T store. Once you get an iPhone, you really can't go back to a cheap phone because it has so many features that cheap phones lack. Anyway. Back to my question. As an iPhone owner, in your opinion, is it true that once you get an iPhone, you can't go back? It definitely is true in my opinion. Edit: FYI, I am 14 and I know more about electronics than either of my parents. But my mom is the executive decision-maker.
