People who know me may find that strange because I'm keen to learn and use an alternate OS on my PC; Linux. However I see that as a completely different affair. For one thing to install Linux I don't have to "hack" my home PC. And I certainly don't have to sign a waiver or risk my internet connection being disconnected. Not only that but installing a custom ROM can be complicated business. If only it were as easy as it is to install a custom Linux distribution on my home PC.
To install a custom ROM on my phone the process goes something like (I've probably gotten this wrong because I've never done it); backup important data, root my phone, install a recovery image, flash the radio, flash a custom ROM (i.e. Cyanogen), and finally reinstall all my apps and data. By that point I'am saying to myself it_shouldn't_be_that_hard. But I digress.
I have found a solution to my tethering needs that will let me tether my phone to either my Windows or Linux (sorry PDANet but you're windows only) desktops and while still using the Rogers officially blessed software for my phone. And it's as simple as it_should_be! Here we go:
1. Install UniversalAndroot (not in the Android market)
2. Run UniversalAndroot and click "Root"
3. Install Barnacle Wifi Tether (should be in the Android market)
4. Start Barnacle and go to Settings
5. Set Custom Wifi Ad-hoc to Hero/Eris
6. Click Start
An ad-hoc wifi network named "barnacle" should appear on your PC for you to connect to. Done!
Maybe one day something will prompt me to I'll install a Cyanogen rom, but it won't be for tethering.
