Not really:
However there are two scenarios in which this is not the case:
1) if you are arrested at the time of the seizure
2) if they manage to find out you moved their new funds off their new phone after they seized the phone
If you refuse to give them the password or the moved funds you can be charged with contempt of court and be placed in jail until you give them the password or the funds. This is a pretty big hassle for them and a lot more work than just taking cash, pre-paid cards, unprotected Bitcoins, etc. so they would have to think the possible profit worth the effort so the amount of, or their perception of, the amount comes in to play.
The "good" news is that this would involve having to arrest and charge you with something so you start to have some rights in the process, can hire an attorney, go to court, etc.
The bad news is that contempt of court charges can not be appealed. Also for all practical purposes there is no time limit for a contempt of court charge. They can give you 30 days, bring you back to court, if you refuse again - another 30 days, rinse and repeat as long as they want.
They kept Martin Armstrong in jail for 7+ years on contempt of court.
The problem is once they do the forensics on your mobile phone and realize you have not given them all the passwords, they will eventually force you to give them all, and then they will be able to track down that you moved funds. Then they will force you to give back those funds, else hold you in contempt of court forever until you do.
Do not keep access to large funds on the mobile phone you carry with you!
I think there might be an even better way. You'd encrypt your password to a public key. At the destination you'd decrypt it with password you had stored at that location. Or just spend the Bitcoins to the new destination address. The point is don't travel with your passwords to large funds.
Don't forget BitCON is centralized mining and thus it will also likely be confiscated with G20 control over the block chain.
My family is much better prepared than I am, as you can see. Alas, in my case, my guns (ammo too) were lost in a boating accident, why a year ago IIRC. Rather than get the police all riled up about guns out there at the bottom of the sea, I thought I would just let them corrode away. Most unfortunate.
Oh, I lost all my precious metals on the same boat-ride. And everyone told me that it was so much better to take all that stuff with me rather than leave it all behind in some dark place at home. How naive. Now I have to start over.
I'm sorry to hear about your loss. Indeed, boating accidents seem to be rather common now. And I had always thought that carrying around my precious and my weapons was a good idea rather than leaving them in some dark hidey-hole at home.
In my case though, I lost all of that while ice-fishing in Minnesota last winter. I even forget which lake. Bummer!
That is not going to work. They will throw you in jail, until you tell them where your gold is. They are not going to believe you lost in the lake.
If you really want to hide assets, there better not be any record of obtaining the assets.
