Hey guys, I have a 3gs jb and unlocked on TMobile, running 3.0.1(7A400) the model is MC137LL modem firmware is 04.26.08

I would like to upgrade to os 4.0.1. is that possible? and still be able to jb and unlock.

Or should I upgrade to 3.1.3 and call it a day. I really appreciate the help everybody. If you can give me a walkthrough it would be incredibly appreciated. I am on PC by the way. Thanks again.

you got your SHSH blobs saved for 4.0.1?

**zeeman04** · 08-15-2010, 03:32 PM

I believe so I go to cydia and it says on top that I do have the shsh files there for this device

should I go with 4.0 or 4.0.1

its up to you, just different signal bars from what Ive heard

**zeeman04** · 08-15-2010, 04:02 PM

ok so with the firmware and model that I have can I upgrade and jb and unlock or am I screwed mate???

**Will13** · 08-15-2010, 04:12 PM

you can jailbreak and unlock anything up to 4.0.1 at the moment, 3.1.3 as good app support in cydia still, but every where else iOS4 is better, and you will need the 4.0/4.0.1 3GS firmware from this website

**zeeman04** · 08-15-2010, 04:15 PM

thanks mate, now please forgive my ignorance, so I need to download the 4.0 ipsw right? then what

**Will13** · 08-15-2010, 04:20 PM

download it, then either edit your host files so they point to cydia's, or download Tinyumbrella and click start TSS server, then in iTunes shift+click restore and pick the FW you downloaded, after you have upgraded and activated, set it up as a new phone so your less likely to have problems, then jailbreak it at jailbreakme.com and install ultrasn0w for your unlock

**zeeman04** · 08-15-2010, 04:22 PM

thanks so much mate, thats awesome thanks for taking the time

**Will13** · 08-15-2010, 04:25 PM

**Will13** · 08-15-2010, 04:44 PM

I dunno, I dont see why thats any different to my MC 3GS

**zeeman04** · 08-15-2010, 04:50 PM

im trying it now I will let you know how it goes. also will i be able to do MMS through TMobile or is that out.

when I do the tinyumbrella and shift restore on itunes does my phone need to be connected to the pc

**Will13** · 08-15-2010, 04:53 PM

yes, otherwise how you gonna restore?, and at first you wont be able to use MMS, but I'll send you a repo in a PM where you can get a patch that makes it work again

**zeeman04** · 08-15-2010, 05:02 PM

**Will13** · 08-15-2010, 05:09 PM

**zeeman04** · 08-15-2010, 05:21 PM
