When you go to Settings > About Phone> Build Number, what do you see for build number?
When you posted it was fixed, I had just found a good 2.2 SBF file for you and was about to post it! Glad you got it.
It has been my experience that once you have a good download and installation of Wireless Tether for Rooted Users (Downloads - android-wifi-tether - Project Hosting on Google Code) (most recent is 207) the next thing you need is a good kernel. So, it doesn't work for you check out P3Droid's kernels (P3Droid Kernels any of the 32.9.7 Kernels) or Raidzero's kernels ([KERNELS] Low Voltage 188.8.131.52 ).

CM recovery is the only tool you need to flash them, or any recovery that will let you install from your SD after clearing data and cache. I name my various ROMs. for example AGP.zip to update.zip and use the install sdcard\update.zip tool
