I've owned an original iPhone since launch and am now ready to upgrade. Im considering iPhone 4 or the Captivate. If the iPhone didn't have antenna issues, I would most likely have already made my decision. However this isn't the case so I'm looking at other options (leaving AT&T isn't one of them). So I just have a few questions regarding Android. Can you backup apps, settings, contacts (everything) to your Mac or PC like an iPhone can? (I know about doubletwist, but thats just music and movies, right?) When Android updates come out, can every phone take advantage of it? For example, if I were to buy the captivate, will I for sure be able to upgrade to Android 3.0? Lastly, what are big features (besides visual customization) that an Android phone has to offer over iPhone? I'm very on the fence about which phone to purchase. There is the potential antenna issue regarding the iPhone 4, however I've also been hearing the Captivate is having its fair share of problems. Any suggestions?
