i made a REALLY stupid decision to jailbreak my iphone 3G on the new 3.0 firmware after having only had it for 3 days and surprise surprise, its stuffed up my iphone. every seemed ok after i jailbroke it, except that there was no reception on the phone but when i plugged it into the computer, i was met with the message "itunes cannot connect with this iphone because of an unknown error" and the device just doesnt show up on itunes at all. i've tried restoring it by putting it into recovery mode (press on/off button for 3 secs, then home button for 10 secs etc ) twice and after the recovery the message just pops back up. i've only had the phone for 3 days!!! and if my parents find out i'm so dead. could anyone who has any expertise on this subject please try and help me i will be forever thankful and i have learnt my lesson BIG TIME
