I got a sony ericsson zylo jazz black today, and was rooting around the menus trying to see if it's possible to put a password lock on the messages... I only want this feature because a "friend" in college keeps taking my phone and reading the messages, even though it's none of his business what's in there... is it even possible to lock the messages on this phone, and if so, how can you do it? i used to have a samsung L700 and i could lock the messages no problem...
