I bought a 620 for my grandmother's birthday, got it in the mail today and unboxed it myself so I could set everything up for her
. That beast is incredibly slick, wow. I bought it from Free in France (they're the only ones selling the phone here, but they sell their phones unlocked and unbranded, <3 Free) where it's only available in white, and it is gorgeous.
Early buyers also got a free additional cover so I got her a blue one, but she'll have to wait a bit for it, as they're all out of stock (for all colors). Seems like these phones are a sleeper hit (and with good reason, 199!).
Orange are the only ones selling the 520, and they're selling it locked and branded unless I'm mistaken, for 189. They're also selling them for a symbolic euro on contract, so I guess that's how they'll sell off the stock, because I can't see anyone buying one full price when the unlocked-unbranded 620 is only 10 more.
