Sidekick software upgrade; adds tabbed e-mail

T-Mobile has released a software upgrade for the Sidekick line of phones. The only element of the phone’s that the upgrade seems to effect is the e-mail browser, which now has the added feature of tabbed browsing. This allows you to check e-mail for several different accounts at once, with your T-Mail on one tab, and your AOL, Yahoo, Hotmail, GMail or whatever other service you might use on other tabs.
