越狱后你仍然可以在手机上开发。解锁后,您仍然可以在手机上进行开发。区别很重要:
越狱:您可以安装应用商店中没有的应用程序。
解锁:您可以在默认运营商以外的其他网络上运行手机(在美国时为 AT&T)。
请注意,您目前无法解锁运行 2.2.1 的 iPhone 3g,如果您购买新的几乎肯定会解锁。您可以越狱 iPhone 和 iPhone 3G。
另请注意,如果您购买新手机,AT&T 将向您收取 200 美元的费用,以解除您的新合同。我认为每月下降 10 或 20 美元,因此一年后,退出计划的成本要低得多。
What I suggest is buying a first generation iPhone on ebay or craigslist. First generation iPhones can all be unlocked, irrespective of whether the previous owner put 2.2.1 on them. Also they are much cheaper, have the camera and are totally fine for software development. I was able to find decent first generation iPhones in Seattle just 2 months ago for about $250 - $350 dollars depending on details. Unlocking/Jailbreaking takes a matter of minutes with QuickPwn, and the phone works great as a development platform.
