A very specific list of requirements

It's time to buy a phone! This time though, for a very picky mother...

No touchscreen, no QWERTY keyboard, just the good 'ol candybar form factor here. Easy, right?

Well, almost. It needs to have Wi-Fi (a rarity on these phones), and it needs to be relatively easy to get hold of in the UK (Orange).

Any suggestions welcome. Thanks in advance.
