How would you ensure a PHONE (iphone/blackberry/etc) is 100% secure wiped?

Say i got an iphone that has mission critical data on it.

or droid.

Given the internal storage, the spare sectoring, how could one be sure 100% that no data could be grabbed off the unit. say if someone with computer forensics background?

What about if your flash ssd drive is damaged? would you give it up to (hp/etc) to repair?

While we can agree bitlocker/pgp is cool; i'm guessing some arms of government (not just the USA) could still brute force it.

Would a magnetic bulk eraser work on nand?
