Online retailers that one can buy a Windows mobile device include Amazon and Overstock. One can also go to their cell phone service provider store or website.
There are several carriers that offer windows mobile phones. Motorola, Cellular One, Boost and T-Mobile, just to name a few.
basically when you need one
Any windows mobile phone will work. (but they will suck, get an iPhone and be done with it.) You can buy one at any cell company. I would tell you to try almost any other phone made. Windows mobile is very problematic.
I assume you want to share an app between two devices, such as two iPhones. No, that is not possible. Each device must buy and download apps for that one device. If you want to change devices, such as when you buy a new one, the apps on the old device are backed up, then uploaded to the new device. Also, any app can be removed, then re-downloaded again later.
Yes. An iPad is a mobile computing device.
I've tried one and they seem quite fast. Slower than some Android devices and the iPhone 4, but faster than phones running Windows Mobile 6.5. Windows Mobile still uses the registry so the more applications installed, the slower the device.
One that can send voice or text messages and receive them as well.
Many mobile device operating systems have some sort of app store where a mobile application can be downloaded. Unfortunately, there does not seem to be an official app for any iOS device. There is a third party messenger app called ebuddy, where you can connect to your Live Messenger account, but the user interface looks very generic and plain.
The best place to download applications for a Windows mobile phone are from the Windows Mobile center on the Microsoft website. One can download applications in a similar way to how iPhone users download from the Apple Store.
One of the best windows mobile dialer in the market is from adoresoftphone.com. The product URL is http://www.adoresoftphone.com/mobile-softphone-windows.html.
