Here’s a list of a few interesting updates related to WP Tango/WP7.5 Refresh:
1. Wifi sharing: This was something that didn’t come with Lumia handsets earlier for whatever reason. But finally, this update will be present with all the WP 7.5 devices.
2. Improved battery life: It is good to see Nokia aware of the average battery life of their Lumia handsets and thus, working upon its improvement. This update is there mainly because some users had reported poor battery life of their Lumia handsets.
3. It is rumored that Lumia Marketplace might be renamed as Nokia Marketplace. The logo would also be Nokia’s Store logo.
These updates sound interesting, isn’t it? Let’s wait for the official press release of Nokia for the final confirmation.
