If you find out how to get around the name look-up problem with your S710, let me know. Luckily I don't have enough names in my address book to make it a big problem but it is irritating.
One interesting note: outside the US, Sony-Ericsson sells the same phone as the S700, which is available only in silver. It's rare that you see the S710 here in the U.S., but when I was in Hong Kong a couple weeks ago, two different people (a waitress and a DJ) both said "Hey, why is your S700 black?". Different world...
