Not true! DFU can be reflashed without internet connection.

@thewelshboyo
Please watch what device You are talking about!!!
Is it 3G or 2G??!!

@thewelshboyo
OK, about first, You talk about 2G phone, that was a lil' messy here.
Second, I have dev account. I was upgrade, I was downgrade, I was do that on win and on mac ( both up/down ) so, what You wanna say? My baseband IS updated to 04.20.01, carrier is T-mobile, phone work without problems, up/downgraded, original/jail, whatever.
So, ... I don't understand why You saying that about 3G baseband?
I will repeat, My posts here is just to help people to get out from things what They had not to do.
Cheers
PS, take this whatever You want....

@rdv099
Take a look one post below ... Thanks for confirm that!

Yeah?! Umm, where, please? Let's everybody ( and here is lot's of interested ) know. Please post link or even send to Me by email and I'll post.

Forget second line. I am serious.
How was You activate phone? I was post here solution to get it update to 3.0 and downgrading from 3.0 to 2.2.1 but WITHOUT GSM module working as it is not possible to activate it without iT and dev. account in the moment on 3.0.
I wasn't say that it's impossible to have 3.0 on 3G, but simply, just to take a peek into it, not to use it if You cannot activate GSM module.
Please, take a pardon, but You are first person who have GSM module working with non-activated phone?
