I can't take credit for it, but someone ported the real GNU wget utility to Android. I found this many months ago and have kept it on my phone. The wget that came with busybox worked great for a while, but after my upgrade to Cyanogen 7 a couple of weeks ago, I noticed several of my Tasker tasks were failing. I finally figured out that it was due to the busybox wget located in /system/xbin/wget. I deleted it and dropped this into /system/bin and everything started working again.
I uploaded it here in case anyone wants it (and so I don't lose it myself.)
Thanks to whoever originally compiled it for Android!
