Hi you guys,

A few days ago something happen to my 3GS IOS4.3.1.

In June I jailbreak my 3GS with Ipad Baseband 6.15.0 and give-it to a friend of mine.

It worked well until my friend tried to upgrade it ... now the problem began ... it never worked no more until few days ago.

Miracle ... divine intervention ... dunno

I was at home , searching a way to downgrade it and I forgot that the 3GS was without battery for few months, I decide to plugged in on my PC, the Itunes decided to charge and then told me that was time to upgrade to version IOS5.0.1 ... and i said - OK then start, i know that you are going to give me a error. Lets try.

That's is the weird part, baseband 6.15.0 was deleted by the IOS 5.0.1 ... it resumed the old version of the baseband. and my phone is working again.

In conclusion, if you have a Iphone with baseband 6.15.0 (phone) try to install again the latest IOS5.0.1. I hope that this was helpful
