If she lost/broke her phone it is very easy to enter the seed again in de Breadwallet app on your new phone IOS/Android, or even borrow a friends phone, load the seed and transfer your BTC.
It was very easy to enter the seed in Multibit, just select Restore Wallet --> Enter your 12 words --> Select Mulitbit Lighthouse BIP 32 and you are done. Take in mind that it takes a while to synchronize the netwerk before your balance appears.
For anyone who is interested, this was the breadwallet support response:
There is currently no way to manually adjust fees. If you receive many small transactions before trying to send out one large transaction, your fee will be quite large. The best solution for this is to have the person sending you funds consolidate them into fewer, larger transactions.
We design our app to be easy for people who are new to bitcoin. Most people don't understand fees or know how to select an appropriate fee, which is why we have left this feature out for simplicity.
Thank you for your understanding.

I hope they make an "expert" modus in the future where we can adjust the fees..
