As they say, the real fun doesn’t start until your device gets root and s-off and that’s certainly the case with the HTC Jetstream. The device got root just a couple days ago and the modders and developers have gone to work making the already great device even greater.
XDA Senior Member Giblet-dono has drawn up a quick tutorial that will give your HTC Jetstream the ability to make and receive phone calls over a 3g GSM network. According to Giblet-dono, all you need to get started is:
S-Off (get yours from HTCDev soon!)
Root (get yours from DoomLord)
That seems like a very short and easy list of pre-requisites. Based on the instructions, it seems just as easy as editing your build.prop file which doesn’t carry a whole lot of risk, so if this sounds like you’d like to try out then head on over to the original thread for the full instructions.
Additionally, Giblet-dono is also working on making messaging work and the up-to-date troubleshooting for it is going on right now in the same thread. It won’t be long until you can use your Jetstream as a fully functional phone. A very large, very awesome phone._________
