I am so lost... Someone please give a noob the path to a wifi tether so Sprint won't rape me. I don't know what i need or don't need I have searched for 2 hours in the forums and now i am giving it to the the android universe. Help...
You have alternatives to wifi tether such as USB and Bluetooth tether which are free from the Market and don't require anything extra. Search for "PDaNet" and "EasyTether". Both are free but have subscriptions to enable "https" domains. Basically they are free as long as you never have to login through a "https" URL. Sites that would carry this are places like Yahoo Email login, Facebook login, MySpace login, etc. After that, most of these sites run on a regular "http" and are free to browse using these apps. The one from PDaNet costs about $10 and it's pretty fast and easy to use. I recommend it and if you'd like to use it how I use it, I can show you a few tricks around the "https" rule.
But, if you want wifi tether, you'll have to do a bit more work.
Either you can purchase Sprint's official one for $30 an extra a month or you can root your phone.
To root your phone is to basically disable security off of the phone and make you, as the user, in 100% ultimate control over the phone. When this happens you are able to do numerous things such as delete apps that came with your phone, customize the look and feel of the phone, and allow wifi tethering without Sprint's official plan.
To learn more about rooting and how to root your phone, head over the the
EVO 4G - All Things Root - Android Forums forum and check out the Rooting for Dummies sticky thread as well as the new Gingerbread Rooting Guide which are both first on the list of threads.
Once your phone is rooted, you have two options:
1. Download a free, generic wifi tethering app from the Market such as Wifi Tether or Barnacle (I do not recommend but it's the easiest way)
2. Get a ROM with tethering enabled. Once you learn about how to root, you'll come across what are known as "ROMs" and each of these typically comes with some sort of way to tether wirelessly as well as through USB. (I highly recommend this route over #1 as the ROMs typically have their own tethering app or have a hacked version of the Sprint app. Either of these run just as well and much better, smoother, and in my opinion, a faster connection.)
EDIT: Sorry I didn't read the above comments before posting...another great place to go for a complete list or ROMs for the Evo is
here.
ASOP based ROMs like MIUI or CM7 (I'm on CM7) have ways of tethering through the ROM itself. For mine, I go under Settings and there is a way to tether either wirelessly or through USB.
Sense based ROMs like EViO and Fresh had hacked versions of the Sprint wifi tethering app in the list of apps. I remember someone telling me that you can get the hacked Sprint app from somewhere else and install it on your rooted phone, but I'll have to find that thread I made.
If you are on the Stock ROM, the Sprint tethering app will work just as it did before and that will only let you tether if you have a plan through Sprint.
