A mobile OS typically starts up when a device powers on, presenting a screen with icons or tiles that present information and provide application access. Mobile operating systems also manage cellular and wireless network connectivity, as well as phone access. Examples of mobile device operating systems include Apple iOS, Google Android, Research in Motionâs BlackBerry OS, Nokiaâs Symbian, Hewlett-Packardâs webOS (formerly Palm OS) and Microsoftâs Windows Phone OS. Some, such as Microsoftâs Windows 8, function as both a traditional desktop OS and a mobile operating system.
The United States Postal Services reports that as of January 2011, it takes an average of one to three days for First-Class Mail to arrive at its destination. Priority Mail takes an average of one to two days to arrive, according to the USPS. USPS only includes the time a package stays in transit in their estimations. Packages dropped off at a post office during business hours usually leave that day. Packages dropped off after hours may take an additional day.
