I know the guys from Coinomi they are Greeks - I assure you they are doing their best and the product is high quality (monero is on their favorite list and I expect them to implement xmr very soon)!
This sounds like great news. Don't think i am stupid by asking this but i will ask anyway, what for can a mobile wallet be usefull ? specific examples i need

And how safe is it , do i upload small amounts onto my mobile account or is it directly connected to the gui wallet ?
