If you are ok now, I should probably wait a little bit before upgrading to 4.2.1 Wed, 29 Dec 2010 02:48:48 +0000 http://blog.iphone-dev.org/post/1359246784#IDComment118487493 http://blog.iphone-dev.org/post/1359246784#IDComment118487150 not clear mate. On the original post you mention 4.0 fw and now 3.1.3; please confirm this. Anyway, if you are at baseband 5.14 and rely on an unlock, check ultra-recycle post. Basically, you need to restore to 4.1 and run redsn0w to JB. Select install ipad baseband to force redsn0w install the 6.15 baseband that can later be unlocked with ultrasn0w 1.2.

The non-unlockable basebands for 3Gs are 5.14 and 5.15, however you can restore to 4.1, run redsn0w to JB, and check the ipad Baseband, (6.15); afterwards unlock with ultrasn0w.

That is the key information you need. Let me know so I can help you out. I assume you need an unlock.

You can rerun redsn0w without clicking Install Cydia, the rest and also not clicking (stupid) multitasking and walpaper. The device will work better that way.

Unless you might be depending on an unlock (if you plan to use it with another carrier) then maybe you should wait as musclenerd + planetbeing are working on it.

Anyway, what I would love, is that Apple would also have included a "force quit" button in each app so you can choose whether to definetly close the app or leaving it on the background, hence avoiding closing and then force quitting them by double-pressing the centre button, tapping and holding, etc... (this is a pain, to be honest). Cheers.

By the way, remember that the first time you load cydia after jailbreaking, it takes quite some time to load...be patient.

It's up to you what to do next.

After that, you should be able to check your current firmware and baseband situation Wed, 9 Jun 2010 02:59:01 +0000 http://blog.iphone-dev.org/post/567311413#IDComment79218389
