Several month back I decided to jailbreak my iphone in order to enable tethering on the phone. I had been using another solution previously but I really wanted to bring my phone up to the newest iPhone OS 3.1.2 and that solution didn’t work with the update.
Jailbreaking my phone was easy to do using blackra1n and I have had no bad effects from it at all.
Now, before you get all judgmental on me, I am not doing this to try to avoid paying any charge that AT&T might add for tethering. AT&T doesn’t offer tethering on the iphone for some reason, and I really need it. Whenever AT&T does start offering it I will gladly pay the extra and use the official tethering method.
Two other huge benefits of the jailbreak are GV Mobile and Siphon. GV mobile lets me easily make calls with my Google Voice number which is what I use for my business phone. Siphon is a SIP voip phone that lets me connect to my Gizmo5 account for making free calls. Google Voice and Gizmo5 give me an easy way to make cheap calls for my business so I don’t use up all my cell phone minutes.
The reason I am writing this now is that I just got off the phone with one of my clients using Siphon and Google Voice. The call quality is excellent and it makes me smile to know I didn’t have to pay anything for the call.
