8 applications can also run in the background in the latest version of WP

According to the latest information, after installing the latest Windows Phone update, up to 8 applications may run in the background on your device.

As previously reported, the latest Windows Phone 7 update will be available to owners as Refresh. Although some information has already come to light about the new system, an important innovation has now been revealed: the novelty also supports running up to 5 programs in the background instead of the previous 8. This is sure to make many happy, as it will make it even more convenient to work on devices running Windows Phone. There’s still no information on when Refresh can reach users, but we certainly don’t have to wait long for it anymore.
