San Francisco ? Google Inc. rules your computer. Now it wants to rule your mobile phone.

In its long-awaited bid to break into the wireless business, Google announced Monday that it has created a broad industry alliance with major phone carriers and handset makers. It also plans to offer a development kit to allow anyone to build free software for mobile phones.

Google hopes that a flood of software would transform mobile phones into more powerful devices, filled with features that let users more easily get driving directions, watch videos and perform other tasks when they are on the go – as quickly and as easily as when they are logged on to their PCs.
