Current Windows Phone 7 handsets like the HTC 7 Trophy or the LG Optimus 7 may benefit from the new Windows Phone Mango update when it is rolled out later this year.
Presented officially yesterday, the next iteration of Windows Phone promises to offer more than 500 improvements, although it was clear to those attending the presentation that Microsoft was focusing on a handful in order not to dilute the message.
Three main features were highlighted during yesterday's presentation; the inclusion of Internet Explorer 9, which brings Mango to the same level as the desktop browser-wise, smarter search results management, thanks to Quick cards and Bing integration and the Local scout feature which intelligently allows apps to communicate and integrate into the Bing Experience.
But there's one hidden benefit which wasn't mentioned openly at the press conference; we've been told by a Microsoft senior executive that Windows Phone Mango may actually improve speed on existing Windows Phone 7 smartphones in a way not dissimilar to what Windows 7 did to Vista computers.
If Windows Phone 7 was good, Mango promises to be much better as Microsoft engineers have been heavily upgrading the code under the OS's hood. For example, some major speed improvements were achieved thanks to a change in the filesystem according to our interlocutor.
Microsoft however won't provide benchmarks or raw data, although playing with the Mango-based phones yesterday clearly showed that they were faster than the existing Windows Phone, noticeably when it came to multi-tasking and any lag between transitions.
