Hi all. Sorry if this question has been asked before. I tried looking but I couldn't find any answers. So I restored (Windows) an iphone 4 with 4.3.3 with 1.59.00 baseband with a custom firmware (downloaded) and it went well with ultrasn0w and all but it seems I cant get internet to work (I have Tmobile data plan) as well as having my "cellular data network" tab missing in my settings. So now I want to create my own custom firmware to see if that'll fix the problems. I went ahead and created a custom firmware with sn0wbreeze using the "baseband preservation mode" and restored with that but it seems my phone is not jailbroken afterward. I'm afraid to use the expert/simple mode because all the tutorials Ive read said that using that will update my baseband? So just to be safe. I'm planning on restoring my phone with sn0wbreeze "baseband preservation mode" custom firmware i created to have my phone restored and baseband preserved. Then jailbreak it using redsn0w and pointing it to the same custom firmware and then installing ultrasn0w to unlock. Would this method work? Any help or advice is greatly appreciated. Thank you!
