Tethering an iPhone

I wrote about jailbreaking my iPhone a few weeks ago and finally had a chance to really give tethering a try.  All in all, a success and I expect I'll use it from time to time.

Originally, I had gotten the Modem app from Cydia and gave it a quick try, but was unsuccessful in large part because I only spent a few minutes on it and I think something was confused with having both the peer-to-peer WiFi and the home WiFi router in the vicinity.  In searching for the instructions for the Modem app again I came across PdaNet so gave it a shot.

The install using Cydia was very straight forward and the instructions for using it were also very simple.  Set up a peer-to-peer WiFi network on my Mac, connect to it from my iPhone, then run PdaNet.  After a moment or two it figured stuff out and created the route from the WiFi to 3G connection and I was online from my Mac.  I didn't have to run anything or configure anything on my Mac other than the peer-to-peer WiFi network and PdaNet appeared to do its thing and then run in the background just fine.

I did a few speed tests and observed between 800Kbps and 1Mbps which I was pleased with, and browsing and retrieving e-mail seemed snappy enough.  What I did notice was that my battery meter was dropping faster than the level of the dog food when my two dogs are given unfettered access to the bag (a story for another day).  It would seem that actively using both WiFi and 3G does drain the battery so having it connected to your computer or otherwise charging is probably required for any kind of sustained use.  I did not use it long enough to see if having it "charging" actually charges it when in use or just keeps it from discharging.

All in all then, a success and I look forward to using it when needed.

Wifi is real power eater. Better use other ways of connectivity. I'm using my phone as modem via bluetooth. Battery life doesn't suffer much and 2MBps are enough to comfortably use net.
