iPhone Rumor Convergence 2009

Both The Register (Rumor rubberizes iPhone 3.0) and Wired (Next-Gen iPhone Specs, Launch Date Revealed) are running iPhone rumor roundup stories.Both blindly missed two obvious and likely candidates for coming new iPhone features. 802.11n, which is a natural and obvious next step in the platform's growth, and rumored here: iPhone 802.11n?update to the next step in the ATT HSDPA (3G) network (along with an updated radio chipset in the iPhone) which will roughly double the speed of the iPhone's 3G network, from 3.6 Mbit/sec to 7.3 Mbit/sec, (See "3G buildout" in this AT&T Ralph de la Vega interview by Engadget), Coming a full week before the WWDC 2009 keynote address, this is an amusing ploy to snatch some eye-balls from the traditional Apple rumor-mongering blogs.

Take a deep breath, and take your time.It's very likely that you can recover your data [NOTES 1, 2] in this situation (a probable bad disk in a RAID 1 mirror). The path to doing so is unfortunately not as obvious as it might seem, and not as obvious as it perhaps should be, but it's pretty simple.Read a whole lot about the subject before you try anything, understand what each tool does before you use it, and then read and think some more before you take the first step.Before You BeginNow, a bit of background.
