iphone 3g 4.0.2 wifi issue- causing no ability to unlock

[sekin67835]

hi,

i have an iphone 3g 4.0.2. I jailbreaked it, but because it is unable to find wifi (seems like everyone who has a 3g that upgraded to 4.0.2 has this problem) i am unable to download ultrasnow. Any ways/ideas in how i can fix this?

If i find a solution i will post it.

Thanks in advance!

additional info:

version (4.0.2(84a400))
modem firmware (05.14.04)

Workaround:

Problem with the phone still:

Wifi and 3g apparently doesn't seem to work.
