We recently came across news of Windows Phone 7.5 “Refresh” aka “Tango” ROMs getting leaked to XDA and now the forum members are revealing the features the update brings which we never knew.

We have come across new addition and features the upadte brings like it increases the multitasking app limit to eight apps which was previously five apps which will make some users happy because they will be able to switch between a lot of apps at a quick time.

The new build also brings more RAM efficiency as the “Tango” build 8773 uses 122 MB of RAM while at the same time the current “Mango” build 8107 uses 153 MB. It also brings MMS delivery confirmation/acknowledgement which is a nice little addition. We’ll keep an eye on the forum to know what more does the update bring and as always we’ll keep you updated.
