Apple iPhone - The iPhone, iPhone 3G, and iPhone 3GS all synchronize with iTunes 9. iTunes 9 works with Windows 7, so there's no need to do anything here. In fact, an added iTunes related bonus will be given, media controls that pop up whenever you pass the cursor over the iTunes 9 box in the Windows 7 taskbar. When an iPhone 3G is plugged into a Windows 7 laptop without iTunes installed, and the OS will treat it like a camera in Devices and Printers.
BlackBerry OS - It was confirmed that BlackBerry users can continue to synchronize their devices with Windows 7 in a BlackBerry Desktop. For example, a BlackBerry Curve 8330, Curve 8320, and Pearl 8130 came up as mass storage devices, while the Storm2 and original Storm offered music and picture synchronization in addition, but none worked with Device Stage.
Feature Phones - Most feature phones still don't synchronize data directly with a PC, though many can do so with over-the-air accounts. For the few devices that can synchronize with the system, the bundled software for Vista should also work with Windows 7.
Microsoft Windows Mobile - Windows Mobile smartphone owners can continue to use Windows Mobile Device Center with Windows 7 just like they do with Vista.
Google Android - The Motorola CLIQ, the T-Mobile myTouch 3G with Google, and the T-Mobile G1 synchronize the data over the air, not locally. The HTC Hero works with HTC Synchronization, a proprietary utility the company hasn't officially approved with Windows 7, but that seems to work fine in testing, according to HTC's Keith Nowak.
It's possible to synchronize a Nokia smartphone using Windows 7 Device Stage. It's just not easy, or even not reliable also. Device Center worked fine with both a Samsung Epix and an HTC Fuze, two Windows Mobile 6.1 phones.
