iPhone 3G 4.2.1 baseband 6.15 Pwnage - iTunes 1600 error
I have an iPhone 3G 8GB. It was on 4.1 (8B117) with modem firmware 5.14.02 (never jailbroken and locked with AT&T).
I needed to unlock it as I m not using AT&T anymore. I went ahead and jailbroke it to 4.2.1 (8C148) and modem firmware 6.15.00 using redsn0w 0.9.6b6 for mac.
I used mac to perform the above procedure. Later, I had a working jailbroken but locked phone. So i fired up cydia (i have a wifi)) and added ultrasnow (and mobilesubstrate as it was a dependency). But the phone kept disconnecting from the wifi all the time and I couldn't get ultrasn0w to install.
So, I used 'iphone explorer' on mac to place ultrasn0w and mobilesubstrate in the iphone directory "var/root/Media/Cydia/AutoInstall". Then I rebooted the iphone and now its completely stuck on the boot screen (white apple logo). It won't start at all.
So, the only way i thought to get it back working was using Pwnage tool and restore using custom ipsw. I used Pwnage Tool 4.1.3 to create custom firmware.
Then i put the phone in DFU mode for itunes to detect it. Itunes detected the phone in DFU mode but cannot restore the custom firmware. I m getting the ERROR 1600 saying the iphone could not be restored.
So, anyone having any information which could help my situation, please let me know.
Could anyone please point me to the right direction. Any help at all would be greatly appreciated.
Thanks in advance

Im pretty sure I am on the I-Pad BaseBand, I tried a recovery through I-Tunes and it gave me the error 1015.

Got the phone working. I just used pwnage tool to create custom firmware (created a custom iOS 4.1.2 not 4.2.1 as 4.2.1 was giving error 1600 while restoring.)
Then restored 4.1.2 using redsn0w and jailbroke and unlocked.(unchecked the update iPad baseband as i was already on 6.15 baseband.)
Worked like charm.
for the error 1015 you can use tinyumbrella(u need java for that), or u can use RecBoot. I used recboot for mac and it worked fine.

I have upgraded my 3G to a custom 4.2.1 that I got from jailbreakmatrix. Baseband was also changed to 6.15 since I check "use ipad baseband".
I make a mistake that I run redsn0w again to enable the battery percentage option. The process couldn't finished up and now my iphone 3g is lock with the cable and itune logo. No matter what I tried, still cannot get out of that.
Please give me an advise what I should do or let me have your custom IPSW since I do not have a Mac computer to create one.

I set my friends phone up with this baseband for the unlock and he did a reset on his phone which made it locked to the "plug in itunes". So i used PwnageTool to create a custome ipsw w/o the baseband but for some reason, it still retrieved the 1600 error code. I've tried using redsn0w to jailbreak it, which went through all the steps, even showing the pineapple and everything. But when it rebooted, it locked onto the "plug into itunes".
But it got it to work. I ran PwnageTool again, but instead of choosing "yes it haz been JB before" , I choosed No. Went through the steps and PwnageTool comfirmed that it was in DFU mode. Went to iTunes and installed the custom firmware and it worked. lol. I guess its just one of those things...
