I just received today one iphone and was trying to make it work with my European sim card when suddenly I lost connection over iTunes and other tools.
Right now I tried many times to I managed to modify WIFI and Internet connection id working perfect on it but when I try to connect to jailbreakme I get blank screen as soon as I press Install AppSnapp and I get no any files from it.

3 hours ago I could access also calculator and other Iphone features but now that I am stucked I can not access them anymore.
My iphone is new iphone v1.1.1 Modem firm... 04.01.12_G and never updated by me or anybody else before except the factory guys.

Please help me someone who is familiar with such problems

ok after I aplied this procedure( Hold on/off and home x 10 seconds) now my iphone is conneted to itunes.
I need to know what iTunes version I need to have to upload the v1.1.1 manually that is on my PC desktop in order to restore it.
