      Wall Street Breakfast: Must-Know News
      FWIW, not all brokerages offer their customers the same access for after-market and pre-market trading, e.g. OptionsXpress allows their users to access to pre-market trading (via the ARCA exchange) from 8-9:30am, not 7-9:30am.

      This was a mystery to me, as I could see trades taking place before I could trade, and I was wondering WHO was trading during hours I didn't have access to! I suspected shenigans, but if you're into trading outside normal hours, it might be wise to inquire what hours are offered.

      For the most part, most pre-market traders tend to ramp up (or sell off) stocks well outside reasonable levels (not to mention over-night trades which are filled at open), and hence why you'll see the market make a quick correction before the price/trend stabilizes.

      Why Apple's iPhone Doesn't Need 3G
      This pretty much repeats my findings of usability of EDGE vs 3G (EVDO): for general internet browsing, EDGE does fine. As stated, latency refers to the delay between the server and the user, and when web-page loads require much communication back and forth, then lower latency times will beat out a faster data transmission rate protocol (e.g. EVDO), for the most part.

      The situation where 3G completely runs circles around EDGE is in heavy downloading tasks, e.g. audio, but especially video, streaming (and up/downloading e-mail is another one, although it's generally not as large an amount of data as video streaming). My EyeTV Hybrid set-up will stream HD recordings on a local netowk via wi-fi to my iPhone (and it looks great!), but the heavy bandwidth demands means you'd have to wait 15 minutes to load even a minute of HD video (optimized for iPhone) via EDGE: just not practical. My Net Monitor program shows bursts of 15MB/sec to support effortless streaming (i.e. video on demand): try doing THAT over EDGE, or even EVDO! It's not going to happen....

      Bottom line: if Apple/AT&T want to enter the video streaming market (and dare I say, viewing live T.V. on the iPhone <gasps!>) then they'll have to get serious about HSDPA/WiMax or some other "real" faster technology. For example, service providers in S. Korea and Japan offer MUCH faster networks that make video streaming a reality today for millions of users, although the network providers there are facing a small technical challenge (tighter population density over smaller areas, etc).
