A few days back we brought you a simple guide to jailbreak your iPhone with firmware 2.1 on your Mac. Well today we are showing some love for our Windows faithful.
This guide will show you how to jailbreak the iPhone 3g only, not the first generation iPhone. Some important notes before we begin: You must have iTunes 8 installed and you must be on firmware 2.1, if you are not, be sure to update via iTunes. Also make sure to go into the task manager and disable ANYTHING Apple or iTunes related.
Let’s get started, after the jump!

How is your battery life doing after upgrading to firmware 2.1? Hopefully better than mine!
I thought everything was going great after I updated Friday morning. Well I had a full charge late in the afternoon and left for work. A half hour later I noticed my iPhone was a bit warm without even using it. I Looked at my battery life and I was at 50% or so! Safe to say the phone was dead not long after.
So after a full night on the charger last night I thought everything should be good today. Well I was wrong. 2 hours of standby and a 5 minute phone call later, and my iPhone looked like the above picture. Actually that is exactly how it looked! What has really got me stumped is that I checked the usage meter and it said I used 1 hour and 56 minutes! A 5 minute phone call turned into that somehow? The time since last full charge was at 2 hours, which was correct.
I did a full restore without using a back up file after this, charged my phone and while the battery did seem to last longer, the battery meter is way off still. The “force quit” did not work, nor did any soft resets.
There is a thread over at Macrumors and Apple Discussions showing others are having this exact same issue, so that leads me to believe that my iPhone is not the issue but rather a issue with the 2.1 firmware in combination with something else? MobileMe possibly?
Turning off Push… my usage meter goes back to normal. Now I’m turning push on for mail only. We’ll see if it messes it up again.
If anyone has had issues like this please chime in.
UPDATE: I am happy to report that ever since I shut off push for contacts and calendars my iPhone is now working like it should. Just woke up and checked the phone, I almost have a full charge and it says I have used 1 hour and 16 minutes and time since last full charge is 10 hours. Which is correct. So it is a issue with mobileme push for sure. Whether it is getting stuck or whatever, if you are having battery issues and use mobileme or exchange try turning off push completely. Then, if it is the issue, slowly turn back on the email push feature and test it out. Then contacts and calendars…
