You better upgrade to windows phone 7.5
If you want to continue being able to download apps from the Microsoft Marketplace portal for Windows Phone apps, you better update to Windows Phone 7.5 soon. One of the more awesome things about Microsoft is that it is quite proactive and transparent when its users need to upgrade. As we wrote earlier, this is one area where Apple can learn a thing or two from Microsoft. Windows Phone users are being urged by the Redmond Washington software giant because key app activities like updating, downloading, and buying at the Marketplace is tied to an overall improvement of the Windows Phone OS. Simply put, without an upgrade to Windows Phone 7.5, users won’t be able to use Marketplace and will not be able to update or get new apps.
To get the phone OS update, users of Windows Phone need to connect the unit to their computer and run Zune software. If they are on a Mac, they do this using the Windows Phone Connector for Mac. What is in the new upgrade? Quite a bit actually, not only will you be able to customize ringtones using your collection of WMA and MP3 files, you can now access voice mail through a visual system, and your battery will probably last longer because the update enables your unit’s battery saver to shut down some features on your phone to squeeze as much battery life out of your system. The update also makes text messaging easier by adding voice-based input.
Other enhancement include building in LinkedIn, Twitter, and Facebook Chat into your phone. Emails are also easier to handle now that the new conversation view lets you group the emails you get by subject. The update also makes it easier to use more than one app at the same time. Maps, Office integration, picture tagging, and video sharing have also been enhanced.
