Restore iPhone 3GS, 3G to iOS 4.2.1 / 4.1 on 06.15.00 Baseband After Using Ultrasn0w 1.2 [How to Guide]

In case you have unlocked your iPhone 3GS / 3G by flashing iPad baseband 6.15.00 with ultrasn0w 1.2 on iOS 4.2.1, and have issues while restoring your device, here is Sherif Hashim the guy behind ultrasn0w unlock tool, has posted a simple guide showing how to restore your iPhone 3GS / 3G to avoid iTunes errors.

Note: To restore your iPhone 3GS from 4.2.1 to 4.1, you must have saved SHSH blobs for iOS 4.1.

For PwnageTool users:

A :  If you are on Mac and use PwnageTool: If you used pwnage tool then you will have to create a “new” custom 4.1 or 4.2.1 and say “No” when you are offered the BB update to 6.15.00 since you already have it, then build the custom ipsw and restore to that.

For Redsn0w users:

B : If you use(d) Redsn0w:

B.1: If you are currently on 4.1, then you can restore to official 4.1 again, and when you see error 1015 pop-up, you kick your device out of recovery mode using TinyUmbrella, use redsn0w and don’t check “ipad BB update” because you already have that Here Is How To Restore iPhone 3G And iPhone 3GS While On Baseband 06.15.00 And Having Issues icon smile

B.2: If you are currently on 4.2.1 then you’ll have to restore back to 4.1 (because 4.2.1 will not allow you to kick the phone out of recovery when 1015 occurs due to the silly BB / iOS mismatch check added there) , then do the same steps as CASE-1.

How to go again to iOS 4.2.1:

If you want to go again to 4.2.1 your only way is to use a custom 4.2.1 done by pwnage tool in the same steps mentioned in A .

Try Hashim's methods above to restore you device between 4.2.1 and 4.1, it worth trying. Don't forget to tell us about your experience.

Greenpois0n Jailbreak iOS 4.2.1 [Soon]

Few minutes ago p0sixninja the hacker behind Greenpois0n jailbreak has just announced that the new version of Greenpois0n is being updated to be untethered jailbreak for iOS 4.2.1 on iPhone 4,3GS iPod touch 4G, 3G and iPad, but the untethered task has caused a delay in releasing the new Greenpois0n.

I apologize for the delay in greenpois0n 4.2.1 support. Our current focus is on a permanent untether solution

Till now there is no ETA (estimate to arrival) for the new Greenpois0n. By the way Comex is also developing a new method to make untethered jailbreak for iOS 4.2.1 on all devices and it's expected to see the light on Christmas.

Fix iPhone 3GS / 3G Battery Drain Problem & Over Heat After Unlock by Ultrasn0w 1.2

The newly released ultrasn0w 1.2 which unlocked the iPhone 3GS/3G running iOS 4.2.1 by flashing the iPad baseband 06.15.00 using Redsn0w 0.9.6b5 or PwnageTool 4.1.3, has caused two major issues for many iPhone 3GS/3G users, ultrasn0w 1.2 has led to aggressive battery drainage, in addition, iPhone becoming excessively hot. Sherif Hashim, one of the hackers behind ultrasn0w has addressed these issues, let's check out them after the jump.

Here's Hashim justifying these issues

i hope those of u with 3g/3gs are enjoying their updated unlocked devices, all props to @MuscleNerd & co. for making this possible :) , hopefully the iphone 4 on 2.10.04 and 3.10.01 follows within a good time table.

on a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it's the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.

The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.

How can you fix these problems:

so to resolve this, u either:
A) 1st Solution: try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it's possible, by any means, try to have an access to one and use it

B) 2nd Solution: if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done

C) 3rd Solution: there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner , which ll resolve that issue for those having it, the details of which shouldn't be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for you

In case you're one of those who suffering from the above mentioned problems after unlocking their devices with ultrasn0w 1.2, you have to try the above solutions as they will handle the situation, but don't forget to feed us back with your results on the comments section.

Steve Jobs Says Software Update Will Fix iOS 4 Performance on iPhone 3G [video]

Steve Jobs has reportedly responded to an email about performance issues with iOS 4 on the iPhone 3G.

I've waited patiently through 4.0.1 and 4.0.2, looking for a fix that will make my phone work again. I've read the forums that advise me to jailbreak my phone or use some other method so I can downgrade back to a version of iPhone 3, however I'm not prepared to use a method that is not supported by Apple.

Software update coming soon.

Sent from my iPhone

It's likely that Jobs is referring to the iOS 4.1 firmware which is currently being tested by developers. This firmware is also thought to bring a fix for the iPhone 4 proximity issues.

The antenna iPhone 4 better than the iPhone 3G

Anandtech has done a series of tests on the quality of the antenna cross iPhone 4 and iPhone 3G, in the light of problems and disputes arising in those days. The study therefore seeks to clarify and put an end to mere "speculation."

We must say that by testing the iPhone antenna 4 was better than the one mounted on the iPhone 3G, but with some clarification to do.

The first test was based on signal quality depending on the power of the same, although the same Andandtech points out that not always the number of "notches" corresponds to the actual signal quality.

The second test concerns the quality of signal based on the location in which the iPhone 4 is held :

As you can see on all terminals signal quality varies according to location, although on the iPhone 4 this difference is accentuated.

But Anandtech also noted that the quality of the antenna on the iPhone 3G is better than 4, especially when the signal is low (below -133), as the call on the new iPhone is much better:

It 'amazing to note the huge difference in signal sensitivity between iPhone 4 and iPhone 3G as the antenna has been improved.

I have no doubt that the reception on the iPhone 4 is better than the other iPhone, even if the "notches" are inferior to 3G.

Eventually AnandTech states that Uses Bumper signal loss is attenuated, and is equated to that of other smartphones.

In practice, although on the iPhone 4 "notches" are less than the 3G, the call quality is superior.
