So cool dude! By using the Mobile Remote software (which cost around $11.99), you can control your PC, Mac, PS3 or any compatible devices by using Xperia X1 smartphone. This software will transform your Xperia X1 into a wireless Bluetooth mouse or keyboard.

Testimonial of a guy who used this Mobile Remote.

Wow you must think that this application is amazing. Yes it is amazing, with this tool you basically can control up to 85% of ps3 functions of your windows mobile ( on iphone??? no sorry they suck lmao) even optical mouse on xperia works fine. First tested out on LBP keyboard chat works fine, then went on to test streaming songs from my laptop works ok, but controls like next songs, last song were missing (maybe i haven’t figure out which button to use =). Internet browsing works well, mouse pad works just like the ones on normal laptops. There are ways to get this software, purchase it from http://www.mobilesrc.com/mobileremote.(is cheap 8.99usd,consider you can get new updates and all the function it has),or google it
