I have great trick.
Actually, I am doing this with my friends. First take any iphone of your friend or any other known person and log in into Facebook with that iPhone. Thus, your Facebook wall automatically seems, that you are using iPhone.
Now, you don’t need iPhone because your friend seems that you are using iPhone. The next step is, open your facebook in computer as “m.facebook.com” and then share your status which seems that you are shared all information from mobile phone.
These tricks will definitely works because your friends know you have used iPhone and here, all status seems updated by mobile.
