i need help on iphone asap please

first of all sorry probably its not the right forum , but didnt know where to make the question.

secondly, i got a friends iphone 4 but i screwed it a little bit , so to make it a little shorter
the iphone 4 is on ios 4.3.5 and baseband 04.10.01.
im searching like crazy for over 10 hours now but cant find a solution.

i read an article about updating to ipad baseband 06.15.00 but i got so tired that i didnt notice that that was a tutorial for 3gs lol.
another problem is that i dont have shsh blolbs for any other firmware but thats not a problem cuz i found a tutorial for how to downgrade to 4.2.1 without shsh blobs.
this is the link
but also i found a tutorial on iclarified that i can unlock my iphone 4 if im on baseband 6.15.00. this is confliting comments that i found on couple of forums.
my idea was to downgrade to 4.2.1 then while jailbraking to go with ipad baseband (06.15.00)
after that to unlock with Ultrasnow. anyone can tell me if this is going to work , or if anyone knows a solution please answer me. ps- gevey isnt a solution for me :$

sry for double posting but im need of any answer asap
so again sorry :$

As of now, there are no free unlocks for iPhone 4 for free other than gevey. Ultrasnow does only work until 3gs. Why go with 6.15.00 since you also now that that's the danger zone to not be able to downgrade.

Also, why do you want to downgrade since ios 4 is really outdated, ie: recent apps doesn't work anymore on an older firmware. The jailbreak for ios6 is officially out by evasion, people are waiting for this and yet you still want to stay oldskul.

Lastly, i tried to help you as i could but your thread is all over the place. pm me if you have more inquiries or just response to the thread.

You must Downgrade 6.15.00 Modem Firmware Baseband!

Plenty of tutorials on YouTube!

I can help you PM me

So how did you screw it? Was it sloppy and all that? lmao

Hope you get it fixed. Next time, don't attempt something you have no clue about, especially if the phone isn't yours.

If you are not techy, well,at this point, you must ask an expert and just pay if needed. After all, you don't want your friend to get mad at you, right?
