Does this mean that I have to wait a bit longer?

I bought an IPhone 3GS to replace my wife's broken cellphone. I am a newbie in the world of IPhone hacking, and I want to confirm that I need to wait a bit longer for additional exploits before I can unlock my version of this phone.

Using f0recast and this link, my phone info is as follows:

Baseband: 05.16.05
Bootloader: 6.4_M3S2
Model: MC132
Jailbreakable: NO
Unlockable: Upgrade to IPad BB

Name: iPhone 3GS
Model: iphone_3gs
Group1: iPhone
Group2:
Generation: 3
ModelCode: iphone_3gs
Machine Model: iPhone2,1
Model introduced: 2009
Production year: 2011
Production week: 37 (September)
Production number: 367 (within this week)
introduced test: GOED
CPU speed: 600MHz
Family name: A1303
Screen size: 3.5 inch
Screen resolution: 480x320 pixels
Colour: White
Capacity: 16GB
Notice that f0recast indicates that my phone cannot be Jailbreakable, but I followed the instructions on this link and it seems to be Jailbroken. I, at least, have Cydia on it. However, I still am not able to use it with T-Mobile (No Service status), but I do have WiFi functioning.

Also, based on this link, my phone seems to have the Toshiba baseband chip instead of the Infineon one, which increases the chances of my phone being bricked with the current exploits and guides available.

What I do not know right now is whether I am able to recover my phone to a clean state (e.g., working baseband) if things go bad during the unlock process. In this forum, the "stickified" topic for recovering an IPhone seems to indicate that any bricked IPhone can be recovered. But other sites indicate that there is no going back once I update the current baseband to the IPad baseband.

So, am I right to assume that my current IPhone is nothing more than an IPod Touch until further exploits are released?

Thanks! Happy New Year!

Use the link in my sig to jailbreak it. Depending on the type of 3GS, I would be weary of using the iPad baseband to unlock it.

base on information you provide, your 3GS was introduced in 2009, therefore it is okay install the Ipad baseband. However, please make sure to search the pros/cons of this Ipad baseband.

3GS introduced in 2011, week 30 or above will have issue with Ipad baseband.

Yep, I was on the RedSn0w site yesterday and got the link for iClarified tutorial there. I used the tutorial with the latest version of RedSn0w.

I'm a bit confused now. My IPhone serial number has 137 in the 3rd, 4th, and 5th digits. Based on this link, any 3GS with greater than 135 in the serial number will likely encounter bricking the phone and losing most of the wireless functionality. Is the information from the link above incorrect?

My bad, I look at the model introduced year and not the production year. Yes, yours will be a problem.

After further reading, I found the following info from this link:

1. There is no software downgrade procedure available once your baseband has been upgraded to 6.15.00. However, @MuscleNerd is currently working on this.

2. If you have a baseband 6.15.00, you will NOT be able to restore using the original firmware. That means iTunes will give you an error message if you try to restore it directly from there. You can only do it via a custom or ‘cooked’ firmware created with redsn0w or other tools such as sn0wbreeze.
Are these statements still valid?

I'm asking because according to this link, I am able to restore my IPhone 3GS' state (including baseband) to a working one.

I have since downloaded iFaith and created a custom, signed IPSW using 5.0.1 IOS. I'm assuming that this custom IPSW package also contains the baseband info (e.g., 5.16.05). If my IPhone is bricked because of the baseband update, then I should be able to restore it using iFaith. Is this a correct assumption?

Thanks!

I bit the bullet and decided to upgrade to the IPad baseband. Before I did this, I decided to use iFaith to backup my IPhone's current state (IPSW IOS 5.0.1 and baseband 5.16.05) just in case the phone becomes bricked during the IPad baseband update.

Since I already had jailbroken the phone using the latest version of redsn0w, I just re-did the jailbreak process, but without installing Cydia. I merely selected Install IPad baseband and acknowledged all the warnings (including the one that stated the incompatibility of the IPad baseband with IPhone 3GS having serial digits greater than 135 for the 3rd, 4th, and 5th digits).

I am happy to report that my IPhone 3GS is currently working with T-Mobile. I, however, cannot verify if the GPS is working. I can confirm that my location on the map seems precised, but I am not sure if this is using other techniques.

I do have one annoyance with my current phone. It seems that after I updated it with the IPad baseband my reboot process is random. By this, I mean that when I turn off the phone and restart it, it gets stuck on the Apple logo for longer than 3 minutes. For the two times that I tried rebooting, I had to hold the Home+Power button to shut down the phone after getting stuck on the Apple logo during restart. I was only able to boot it properly by plugging the phone while in the off state via the USB connection to my PC.
