用于 iPhone 开发的 iPod touch
我正在考虑购买 iPod touch，以便通过为 iPhone 开发应用程序来赚点钱。 我喜欢 App Store 的概念，并通过 iTunes 快速了解了它。 看起来应用程序已分类，为 iPhone 或 iPod 应用程序。 一些对 iPod 免费的应用程序对 iPhone 用户来说似乎是收费的。
这两个平台有什么区别，或者为什么 App Store 将它们分开？ 使用 iPod touch（除了与电话/位置相关的应用程序之外）为 iPhone 进行开发有意义吗？
在developer.apple.com 上，我可以注册在AppStore 上以99 美元的价格销售我的应用程序。 我需要承担任何进一步的费用吗？ 从美国以外的地方（在我的例子中是德国）开发有问题吗？
I am thinking about buying an iPod touch to make some money on developing apps for the iPhone. I like the concept of the App Store and had a quick look at it with iTunes.
Looks like applications are categorized, to be iPhone OR iPod applications.
Some apps which are free for the iPod seem to cost for iPhone users.
What is the difference of both platforms, or why is the App Store separating them ?
Does it make sense to develop for the iPhone using an iPod touch (beside phone/location related apps) ?
On developer.apple.com I can sign up for selling my Applications on the AppStore for 99$.
Do I have to expect any further costs ?
Is it a problem to develop from outside the US (in my case Germany) ?

我目前使用 iPod Touch 进行开发测试，但我的应用程序（当前）不使用任何 iPhone 独有的功能（例如 GPS 或相机）。
除了硬件差异外，操作系统是相同的，并且 iPhone 需向手机运营商支付月费。
在 AppStore 中，您可以将您的应用程序标记为“仅限 iPhone”或“iPod & iPhone”。 iPhone。 如果您的应用程序需要详细的 GPS、拍照功能等，您将仅将其设置为 iPhone。
除非您发布该应用程序的两个单独版本，否则无法根据用户拥有 iPod 还是 iPhone 来为应用程序设置单独的定价。
I currently use an iPod Touch for testing in development, but my application doesn't (currently) use any of the iPhone-only features (such as GPS or the camera).
Other than the hardware differences, the OS is the same, and the iPhone comes with a monthly fee from the cellphone carrier.
In the AppStore, you can mark your application as iPhone Only or iPod & iPhone. If you application needs detailed GPS, photo taking capability, etc you'll make it as iPhone only.
There is no way to set separate pricing for an app based on whether the user has an iPod or iPhone, unless you release two separate versions of the application.

比 iPhone iPod touch
无麦克风（iPod Touch 4G 有带麦克风的耳机 ，我建议使用iPhone。
在我看来，开发适用于 iPhone 和 Touch 的应用程序将会扩大市场。

iPod touch Cons:
So, I will suggest going for iPhone.
In my opinion, developing an app both for iPhone and Touch will increase the market.
我使用 iPhone 3G、iPhone 2G 和（原始）iPod Touch 进行开发。 我真的很喜欢能够在所有可用设备上进行测试。
I use an iPhone 3G, iPhone 2G and an (original) iPod Touch for development. I really like to be able to test on ALL available devices.
我发现使用 iPod touch (2G) 的最大问题是它更快
比iPhone。 如果你正在开发游戏，那就很严重了。 我找到了
iPhone 3G 比我的 iPod 慢大约 10 fps，所以在提交应用程序之前我可能不得不花钱买一部 iPhone。 我真的不期待那种普通的电信合同中的施虐受虐关系。
The biggest problem I've found with using the iPod touch (2G) is that it's faster
than the iPhone. That's serious if you're working on a game. I've found the
iPhone 3G to be around 10fps slower than my iPod, so before submitting the app I'll probably have to shell out for an iPhone anyway. I'm really not looking forward to the sadomasochistic relationship that is your average telco contract.
如果您的目标是开发，我建议您跳过 iPod Touch，直接转向 iPhone。 它具有更多功能（GPS、蓝牙、蜂窝网络和摄像头），这使得实际使用的潜在应用范围更广泛。
I would recommend skipping the iPod Touch and going straight to the iPhone if development is your goal. It has more capabilities (GPS, Bluetooth, Cellular network and Camera) which makes for a wider range of potential applications that may actually be used.
iPod touch 丢失：
https://stackoverflow.com/users/1450/john-topley">John 侧面它的重量更轻，更小。除此之外，它们几乎完全相同（这里没有讽刺；它仍然具有相同的处理器、操作系统、控制系统和显示屏）就我个人而言，我会买一部 iPhone，就像你一样无论如何，最终可能会得到一个。 我有一个 iPod touch（先买的）和一个 iPhone。 我再也没有使用过 iPod。
iPod touch 显然比 iPhone 便宜，而且不需要签订合同。 不过，至少在英国你可以买到一部无合约 iPhone，而且你应该很快就能在美国的 AT&T 上买到。
除了 99 美元的应用程序开发费用（年费）外，没有任何额外费用，
我们在英国进行开发。 当您最终出售应用程序时需要注意的一个问题是预扣税 - Apple 将保留您收入的 30%。 您需要填写一些表格 - 我在另一个线程。 这是我在那里写的：
您需要填写W-8BEN 并将其交给 Apple，以避免 30% 的预扣税。 这要求您拥有 SSN（社会安全号码）。 当且仅当您没有 SSN 时，您才可以提供 ITIN（个人纳税人识别号）或 EIN（雇主 ID 号）。
要获取 ITIN，您需要填写表格 W7 并提交给国税局。
The iPod touch is missing:
On the plus side it weighs a bit less and is a bit smaller.. Other than that they are pretty much identical (no sarcasm here; it still has the same processor, OS, control system, and display) Personally I would get an iPhone, as you will probably end up getting one later on anyway. I have an iPod touch (bought first) and an iPhone. I never use the iPod anymore.
The iPod touch is obviously cheaper than the iPhone, and there is no contract necessary. However, at least in the UK you can get a contract-free iPhone, and you should be able to do so soon on AT&T in the USA.
There are no extra costs besides the $99 for application development (which is a yearly fee)
We are developing from the UK. One issue to be aware of when you eventually sell your application is tax withholding - Apple will retain 30% of your revenues. There are some forms you need to fill out - I dealt with this in another thread. Here's what I wrote there:
You need to fill out a W-8BEN and give it to Apple to avoid a 30% tax withholding. This requires that you have a SSN (Social Security Number). If, and only if, you do not have an SSN, you may supply an ITIN (Individual Taxpayer Identification Number) or an EIN (Employer ID Number).
To get an ITIN, you need to fill out form W7 and submit that to the IRS.
