Yes, it's possible. I personally managed to complete level 6 three or four times, but my girlfriend hates me, because of it
There's also a guy in the Android Market comments, who claims that he has completed the campaign.
To complete it, try to make a good use of the rotation function to rearrange the bubbles (rotate the phone upside-down).
If you still can't complete the level in several days, I'll make a walkthrough.
BTW, keep in mind that level 11 is harder. It will be your worst nightmare
