My accent is british, kind of south London accent but a tiny bit of north London in it too.
Tumarto/Tamarto
Putato/Patato
We don't really say Soda or Pop.. we just call it by it's product, e.g coke, sprite, fanta, etc.
I also say Zee instead of Zed when I recite the alphabet (last time I checked anyway, don't exactly do it every day), and I have Sesame Street to blame for it.
