This is something I am going to try with either limera1n http://www.limera1n.com or greenpois0n http://greenpois0n.com. Why? Because I want to be able to finally call my friends' iPods with FaceTime by email. :) I want to keep my unlock with ultrasn0w http://ultrasn0w.com.

P.S. Fresh update - you can not do limera1n with ultrasn0w, so do either greenpois0n, which might also be not an option, if they incorporate limera1n's exploit, or DevTeam suggests to wait PwnageTool http://blog.iphone-dev.org/post/1280823486/limera1n-surprise

iPhone 4 battery drain. Solved.

A quick follow up to http://live.prokhorenko.us/iphone-4-jailbreak-battery-drain

What I tried. Restore to 4.0.1 (not 4.0.2 or you will loose a jailbreak). Jailbreak. Install only MyWi4 from Cydia with Rock, run MyWi4, get the first license, remove MyWi4, install Elpelle6's MyWi4 without Rock, remove Rock - now you've got pretty clean jailbroken iPhone4 with MyWi4 without Rock installed. Run MyWi4 - it will ask you to respring. I told it "Later" and probably that what helps. It does work anyways - I tried it.

The battery runs out a little bit (I still believe MyWi4 is sorta dirty), but it's acceptable - under 5% overnight. Hopefully, it will work for you, too.

iPhone 4 jailbreak battery drain

I have recently used jailbreakme.com to make my iPhone 4 free. However, fairly soon, I've discovered that I have a significant battery drain with it. It took literally overnight to drop my 25% from fully charged one. So I decided to took few tries and find out who's responsible for this leak. On that particular jailbroken version, it was going down to 87% with 30 mins of usage and 3 hr 42 mins of standby time.

The clean restored iPhone stays for 32 mins of usage and 4 hr 47 mins of standby, and goes down to 95% only! That's more than 3 times. Not good.

Next, going thru the jailbreak, not touching Cydia or any apps. iPhone stays for 17 min of usage and 3 hr 35 mins and down to 96% only. Basically, that's a sign that jailbreak indeed doesn't drain the battery.

Next, installing all of the updates that Cydia wants you to. It took me overnight to measure it, but seeing 15 min of usage and 9 hr 33 mins of standby and down to 95% only is clearly a good indicator of no battery drain going on.

The last step was to install MyWi 4.3.4. It comes also with Mobile Subtrate. After spending some time with it - 1 hr 17 mins of usage and 5 hr 45 mins standby - brought my phone down to 78%, which is definitely stands out of the line of "good battery usage". So, either Mobile Subtrate is draining the battery or MyWi didn't do a good job writing an extension to it, and now it eats all he juice.

I'll keep you updated, but I'm already upset so much - the most important reason for me was free tethering - and now I feel that I'm paying too big premium for it.

Troubleshooting unlocked & jailbroken iPhone 4

For those who haven't tried yet. Jailbreak worked flawlessly on my iPhone 4. Unlock was relatively easy, too.

I also installed MyWi 4 (the major reason for actually jailbreaking my iPhone, I really need a device to tether on the way) and My3G. Besides, I've installed Open SSH server and SB Setting, to be able to turn the SSH server off. After that, problems started to appear. The biggest one was FaceTime turned off and not being able to turn on. It actually started to send freaking short messages to some +44 number (I guess I'd be quite upset with upcoming AT&T bill), and I started to receive some replies back. Installing iPhone Delivery (which was recommended to early users of jailbreak) didn't solve the problem. I stopped receiving replies (although, I'm not sure I'm not billed for them :), but FaceTime failed to activate.

Uninstalling My3G did the trick. Easily activated FaceTime after that, and it started to work well. Reinstalling My3G after, kept FaceTime activated, but every time I tried to connect thru FaceTime it was failing. So, I'm ending up with no My3G, which makes the overall experience less exciting, but I hope this problem can be solved soon.

Leaked iPhone 4 troubleshooting guide

1. Keep all of the positioning statements in the BN handy – your tone when delivering this information is important.

a. The iPhone 4’s wireless performance is the best we have ever shipped. Our testing shows that iPhone 4’s overall antenna performance is better than iPhone 3GS.

b. Gripping almost any mobile phone in certain places will reduce its reception. This is true of the iPhone 4, the iPhone 3GS, and many other phones we have tested. It is a fact of life in the wireless world.

c. If you are experiencing this on your iPhone 3GS, avoid covering the bottom-right side with your hand.

d. If you are experiencing this on your iPhone 4, avoid covering the black strip in the lower-left corner of the metal band.

e. The use of a case or Bumper that is made out of rubber or plastic may improve wireless performance by keeping your hand from directly covering these areas.

2. Do not perform warranty service. Use the positioning above for any customer questions or concerns.

3. Don’t forget YOU STILL NEED to probe and troubleshoot. If a customer calls about their reception while the phone is sitting on a table (not being held) it is not the metal band.

4. ONLY escalate if the issue exists when the phone is not held AND you cannot resolve it.

5. We ARE NOT appeasing customers with free bumpers – DON’T promise a free bumper to customers.

Quite interesting leaked guide for AppleCare representatives on how to troubleshoot (and keep the iPhone in hand) when being asked about reception problem. The bad thing is that they decided to go against the customer.
