1.1.2 OTB upgrade to 1.1.4 Question

Alright so I have a 1.1.2 OTB BL 4.6 and it was unlocked using a T-Mobile and I was using a Next Sim v4.

Ok so then I decided to upgrade my iPhone to 1.1.4 using ZiPhone 2.5c - What I did was I went to Advance Features/only clicked on "Erase BL 3.9 Baseband.

Now once I did that, I noticed that everything was reset as if I just got the phone. So i hooked it up to iTunes and it had that option to restore contacts. So i clicked on restore and then all of a sudden I didnt have T-Mobile and it just said "searching".

I assumed that it wasnt working anymore for T-Mobile so then I clicked "Do it All" on ZiPhone 2.5c, now it did what it had to do.

I had 1.1.4 firmware and then a 04.04.05_G BL.

Now my question is, wasnt I supposed to have the 3.9BL? And can I restore it back to the orignial factory settings as if I baught it? 1.1.2 OTB?

Please help thanks!

You can not go from regular 3.9bl to4.9bl right now. To check your bootloader version install hardware info from the intsaller and see. If you have 3.9bl then no its not like it was when you got it so then your stuck with 3.9 for the time being
